Verified math for humans and AI agents
Exact Greeks, IV and payoffs for options, plus forex pip math, Sharpe ratios and VaR, prediction-market odds, on-chain safety checks, and perpetual futures PnL and liquidation. Every MCP result is signed, and every formula is published.
Computed by the same functions the MCP tools call. Open any row to change the inputs.
d044e19f1a387c022044345c9c6c14c681f9dd206a9fe65ce84ae6d288b209a8Every number comes with proof.
Four ways to check any result yourself.
Signed results
Every MCP result carries an ECDSA P-256 signature. Confirm offline that it came from us, unchanged.
Public test vectors
60 canonical vectors and 2,000+ tests on every deploy. The live report reruns the vectors on every visit.
Daily record on Solana
Every day a hash of the signed verification state is written to Solana. Past records cannot be quietly changed.
Tested against AI models
Each month we test current AI models on fresh tasks of the same kinds. October 2026: 97% right, and most misses came with high confidence.
Calculations only. No trade advice, no execution, no price predictions.
LLMs get most trading math right. You cannot tell which answers they got wrong.
6 current models from OpenAI, Anthropic and Google got 97% of our trading-math questions right in October 2026. 12 of their 17 wrong answers came with 80%+ confidence.
Confident wrong answers
A VaR 2% too high, stated with 100% confidence. A losing short reported as a win. Both read like any other answer.
SEE THE TEST RESULTSVenue and market conventions
Deribit settles options in the coin while Binance settles them in USDT, forex quotes a pip differently on JPY pairs, and every exchange defines margin, fees, and funding its own way. A generic formula is wrong almost everywhere.
Workflow fragility
One bad liquidation estimate or sizing error breaks the whole execution flow. Recomputable numbers let you find it fast.
Options math, computed the way the venue actually settles it
Payoff and breakeven for a single-leg call/put, plus Black-Scholes price and Greeks: manual, or checked live against a real Deribit or Binance option's own quoted price. The payoff calculators follow Deribit's coin settlement.
Black-Scholes Calculator
Theoretical option price and Greeks (delta, gamma, theta, vega, rho) from Black-Scholes: manual inputs, or pulled live from a real Deribit (BTC/ETH, coin-settled) Binance (BTC, ETH, gold, silver, USDT-settled) or Bybit (BTC, ETH, USDT-settled) option to check whether its quoted mark price is consistent with its own implied volatility.
Options Payoff Calculator
Payoff, P&L, and breakeven price for a single-leg Deribit (coin-settled) or Binance (USDT-settled) option (long/short call/put) at any scenario price: pure settlement algebra matching how each venue actually settles.
Straddle & Strangle Calculator
Combined payoff, both breakeven prices, and max loss/profit for a long or short Deribit (coin-settled) or Binance (USDT-settled) straddle or strangle: same convention as the single-leg payoff calculator, summed across both legs.
Covered Call & Protective Put Calculator
Annualized yield (covered call) or insurance cost (protective put) plus position value at any scenario price, for coin held against a Deribit (coin-settled) or Binance (USDT-settled) option leg; on Deribit it accounts for the coin-denominated premium's effect on the cap/floor.
Implied Volatility Calculator
Solves for the volatility Black-Scholes needs to reproduce an observed option price: Newton-Raphson with a bisection fallback, and a no-arbitrage bounds check that refuses to solve an impossible price rather than return a garbage number.
Spread & Iron Condor Calculator
Payoff, breakeven(s), and max profit/loss for a vertical spread (2 legs) or iron condor/butterfly (4 legs): on Deribit (coin-settled) max profit/loss and breakevens are genuinely not the flat textbook values; Binance (USDT-settled) uses the flat textbook payoff.
Barrier Touch Calculator
Probability that price touches a target or stop level at any time within N days (geometric Brownian motion, reflection principle with drift), next to the probability of finishing beyond it: a touch is roughly twice as likely as a finish (exactly twice at zero log-drift), so pricing one with the other is off by about a factor of two. Continuous monitoring, 365-day year, constant volatility.
American Option Calculator
American put or call price on a Cox-Ross-Rubinstein binomial tree (50 to 2000 steps) with a continuous dividend yield: delta, gamma, theta per day, an exercise-now flag, the European Black-Scholes price beside it and the tree error at the chosen step count. For stock and ETF style options that can be exercised early.
Option Greeks Calculator
First and second order Greeks of a European option with a dividend yield: delta, gamma, vega, theta, rho, vanna, vomma, charm, veta, speed, zomma and color, each with a one-line explanation. Checked against QuantLib and 100-digit differentiation on 1000 random options.
Options Profit Calculator
Profit and loss at expiry for a stock, ETF or index option position of 1 to 4 legs, in dollars with the 100-share contract multiplier: breakeven prices, max profit and max loss (or unlimited), net debit or credit, with presets for spreads, iron condor, iron butterfly, straddle, strangle and covered call. Prices are the ones you type; nothing is fetched.
Options Strategy Picker
Ranks option strategies (spreads, straddle, strangle, butterfly, iron condor, covered call, protective put and more) for your price forecast and your view on volatility: expected profit, probability of profit, max loss and breakevens for the best strikes of each, priced with Black-Scholes at one implied volatility. Nothing is fetched.
Max Pain Calculator
The strike where holders of all calls and puts of one expiry would be paid the least, from the live open interest of Deribit (BTC, ETH, coin-settled), Binance (BTC, ETH, gold, silver) or Bybit (BTC, ETH), or from open interest you type: the payout at every strike, the put/call open-interest ratio and the distance from the price today. A descriptive statistic of open positions, not a forecast.
Cash-Secured Put Calculator
Premium income, cash held, return for the period and per year, the effective buy price if the shares are assigned, the breakeven and the loss below it for a put sold against cash on a stock or ETF, in dollars with 100-share contracts. Optional comparison with buying the shares now. Prices are the ones you type; nothing is fetched.
Pip and lot math, the same deterministic way
Pip value, margin, breakeven, PnL, risk/reward, scenarios, position size, swap and correlation, with conversion into your account currency at a live FX rate. Pip and lot conventions are verified against real broker documentation.
Pip Value Calculator
Value of 1 pip for a given pair and position size, in that pair's own quote currency: universal pip-size convention (0.0001, or 0.01 for JPY pairs), no live data needed.
Margin Level Calculator
Free margin and margin level % from account equity and used margin: the same stop-out proximity metric every forex platform shows, computed directly.
PnL Calculator
Profit or loss for a closed or hypothetical forex trade, in pips and in the pair's own quote currency, long or short.
Risk/Reward Calculator
Risk and reward distance in pips from entry/stop/target, and the resulting ratio: a raw number, not a verdict.
Currency Converter
Converts an amount between currencies using a live FX rate: TrueFX for its 10 major pairs, frankfurter.app daily rate as the fallback.
Position Size Calculator
Position size in lots from a risk amount and stop distance, sized in your account currency via a live FX rate.
Risk and return statistics, the same deterministic way
Value at Risk, a Sharpe ratio corrected for serial correlation (not just the naive sqrt(q) scaling), the Hurst exponent, Engle-Granger cointegration for pairs trading, and a portfolio tearsheet: same deterministic, formula-verified layer as everything else.
VaR / CVaR Calculator
Parametric Value at Risk and Conditional VaR (Expected Shortfall) from a return series or a direct mean/stdev, at any confidence level, plus a skew/kurtosis-aware Modified (Cornish-Fisher) VaR.
Sharpe Ratio Calculator
Sharpe ratio with the Lo (2002) serial-correlation-aware annualization correction (not just the naive sqrt(q) scaling), plus the Probabilistic Sharpe Ratio (Bailey & Lopez de Prado).
Hurst Exponent Calculator
Rescaled-range (R/S) Hurst exponent: is a return series trending/persistent (H>0.5), mean-reverting (H<0.5), or consistent with a random walk (H~0.5)?
Portfolio Tearsheet
Core risk/return tearsheet from a return series: annualized return/volatility, Sharpe (plain/Lo/Adjusted), Sortino, drawdown-ratio cluster (Ulcer/Martin, Pain, Burke, Omega-Sharpe, Upside Potential Ratio), skew/kurtosis, PSR, win rate.
GARCH Volatility Calculator
GARCH(1,1) volatility model fit by maximum likelihood on a return series: estimates omega/alpha/beta persistence and forecasts next-period volatility.
Risk Parity Calculator
Risk-parity (equal or custom risk contribution) portfolio weights for N assets, from a covariance matrix or raw return series.
What does the market actually imply?
Reads live crypto-price markets across 5 independent venues: odds conversion, cross-venue spread checking, the market-implied BTC/ETH year-end price ladder (Kalshi), and edge sizing with fractional Kelly.
Probability Calculator
Converts a probability (manual, or pulled live from Kalshi, Polymarket, ADI Predictstreet, Limitless, or Myriad) into decimal/American odds and the breakeven win rate, plus the vig when a live market gives both sides of the price.
Market-Implied Odds
Reads Kalshi's live BTC/ETH year-end price ladder and reports what the market itself implies: median and mode price bucket, and probability at/above any real bucket boundary. No invented interpolation.
Kelly Calculator
Compares your own probability estimate against a Kalshi, Limitless, or Myriad market's price (manual or live) and sizes a bet with fractional Kelly: edge, expected value per dollar, and a capped recommended stake.
Up/Down Fair Value
Theoretical fair value for a time-windowed crypto up/down contract (ADI Predictstreet, Kalshi-style dailies) via the digital-option formula: for venues/windows with no live market price yet.
Spread Checker
Reads the same real-world bet's live price from 2-5 venues at once (Kalshi, Polymarket, ADI Predictstreet, Limitless, Myriad) and reports the spread between the cheapest and most expensive. Never auto-matches events across venues; you supply each venue's own identifier.
Arbitrage Checker
Checks 2-5 venue quotes (or manual probabilities) for the same bet for a guaranteed, direction-independent profit: buy Yes at the cheapest venue, No at the priciest, reports the guaranteed profit for a given stake and whether trading fees erase it.
Solana + 5 EVM chains, checked before you click confirm
Rug-pull mechanism checks, swap price impact, bonding curve math, market-cap comparison, and wallet flag checks: sourced and timestamped, not a guess.
Rug Pull Checker
Solana token safety spot-check: mint/freeze authority, LP lock, mutable metadata, named scam-pattern flags, sourced and timestamped. Holder concentration shown separately as market context.
Swap Price Impact
Live price-impact quote for a Solana swap, routed through Jupiter across every pool it knows about, not a single-pool estimate.
Bonding Curve
Pump.fun-style bonding curve calculator: exact tokens received, price impact, graduation progress. Pure constant-product math from pump.fun's official reserve constants, no live lookup needed.
Market Cap Calculator
Live market-cap ratio between two tokens (Solana or 5 EVM chains, mix and match), projected onto an investment. Narrative-agnostic, works for any token pair.
Wallet Checker
Checks a wallet (Solana or 5 EVM chains) against independent flag databases (GoPlus, Webacy, ScamSniffer on EVM): sanctions, phishing, mixers, exchange labels, shown separately, not merged into one score.
Impermanent Loss Calculator
Impermanent loss for a liquidity-pool position, full-range or Uniswap-V3-style concentrated: LP value vs. simply holding, at a manual price or live-fetched from the pool's two live token prices.
What did that coin actually make you?
Profit, ROI and the break-even sell price for a coin you bought and sold, after the buy fee and the sell fee. No leverage, no funding.
Crypto Profit
Profit or loss on a spot crypto buy and sell after both fees: coins bought, total cost, proceeds, ROI, the break-even sell price and, for a hold of 30 days or more, the annualized return.
Crypto DCA
Dollar-cost averaging into a spot coin: the same cash at each of a list of prices gives the average price paid, coins held, cost per coin with fees, the break-even sell price and, with a current price, the profit and ROI.
Average Buy Price
The real entry price of a spot coin after several buys and sells, each with its own fee: average buy price of what you hold, cost basis, realized profit and the break-even sell price.
Target Sell Price
The price to sell a spot coin at for a target return or a target profit after both fees: the inverse of Crypto Profit, with the break-even price next to it.
What is that money worth, and when?
Discount a future sum, grow a deposit, test a project's cash flows, or find the rate that links two values. Rates are stated, conventions are published, and an IRR with more than one answer says so.
Present Value
What a future sum, a stream of level payments or both are worth today at a given annual rate: present value, the share from each part, the discount factor and the effective annual rate.
Future Value
What a sum today, regular deposits or both grow to at a given annual rate: future value, interest earned, total contributions and the effective annual rate.
NPV
Net present value of a list of cash flows at a discount rate, with the time-0 flow undiscounted: NPV, each flow discounted, the present value of inflows and outflows.
IRR
The internal rate of return of a list of cash flows: the rate that makes the net present value zero. Reports every rate found and says so when the flows have more than one answer.
CAGR
The constant yearly growth rate between a starting and an ending value over a number of years: CAGR, total return and growth multiple.
APY / APR
Convert an APR to an APY or back with the compounding you choose (daily, weekly, monthly, quarterly, continuous): the converted rate and the same APY as an APR at each frequency.
Bond Price
Price of a fixed-rate bond at a yield to maturity, with Macaulay and modified duration, convexity and DV01: how much the price moves for one basis point.

Why not let the LLM calculate this directly?
LLMs approximate. For liquidation prices, funding costs, and position sizing the difference between "close enough" and right can mean a blown position. TradingCalc gives your agent a published, tested formula with its assumptions stated: the same inputs always give the same number.
Are the calculations deterministic?
Yes. Same inputs always produce the same outputs: no randomness, no estimation. Every formula is regression-tested against 60 canonical vectors and verified on every deployment.
Which exchanges are supported?
For perpetual futures, 17 exchanges, including Binance, Bybit, OKX, Hyperliquid, Kraken, Deribit, and dYdX. Live prices and funding rates come from each exchange, and each exchange page lists that exchange's base trading fees. The formulas themselves are general, so an exchange's own liquidation engine (size tiers, liquidation fee) can show a slightly different figure.
Is TradingCalc a trading bot or execution service?
No. TradingCalc provides deterministic calculations, not trade advice, execution, or market predictions. You build the strategy; we give you the exact numbers.
Can I use this in a trading bot?
Yes, that is the primary use case. The MCP server returns structured JSON your bot can parse directly, through an MCP client or a plain HTTP call. No scraping, no parsing free-form text.
What is a workflow?
A workflow answers a specific trading question: "Is this trade worth taking?" or "What is my carry yield?" It orchestrates multiple calculators in one call and returns a verdict plus plain-English explanation, not just raw numbers.
How do I get an API key?
Email s@tradingcalc.io: a free API key raises your rate limit to 200 calls/day. Anonymous use (100/day) needs no key at all.
Will you add more exchanges?
Yes. New exchanges are integrated regularly. Contact s@tradingcalc.io if your exchange is not on the list.
Is TradingCalc only for crypto perp futures?
No. Options, forex, and risk/stats math do not depend on the market, and the same deterministic layer also covers prediction markets, on-chain safety, crypto spot trades, time value of money, and perpetual futures: eight domains total, one MCP server.
