calculate_atr_stop
A volatility (ATR) stop: entry minus (long) or plus (short) a multiple of the average true range. Give atr, or at least five recent daily ranges (high minus low). Computed with the same function as Clear Tape's free atr stop-loss calculator page (linked in the result), not estimated. Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_drawdown_recovery
The gain needed to recover from a drawdown and, optionally, how many losing trades in a row at a fixed risk per trade cause it.

Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_expectancy
Expectancy per trade, per 100 trades, payoff ratio, break-even win rate and profit factor from a win rate and average win and loss. Computed with the same function as Clear Tape's free trading expectancy calculator page (linked in the result), not estimated.

calculate_kelly_criterion
Full and fractional Kelly risk per trade from a win rate and payoff ratio, with the edge per 1R and the break-even win rate.

Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_losing_streak
The exact probability of at least one losing streak of a given length over a number of independent trades, the expected longest streak and the streak 95% of sequences stay within. Computed with the same function as Clear Tape's free losing streak calculator page (linked in the result), not estimated. Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_position_size
Position size from the stop: how many shares to buy (or short) so that a stop-out loses a set percentage of the account. Computed with the same function as Clear Tape's free position size calculator page (linked in the result), not estimated. Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_risk_reward
Risk/reward ratio of a planned trade, the win rate it needs to break even, and (optionally) an exit expressed as an R multiple.

Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.
calculate_trading_cost
The cost of one round trip (commissions, bid-ask spread, slippage) in USD, in R, as a share of the target move and of the position, and over a year of trades. Computed with the same function as Clear Tape's free trading cost calculator page (linked in the result), not estimated. Returns the inputs, each result with its unit, the formula and the page link. Educational, not investment advice.

lookup
lookup_glossary_term
Looks up a trading term in Clear Tape's bilingual (English and Simplified Chinese) glossary of about 70 terms, such as "R multiple", "ATR", "drawdown" or "止损". Matches names, abbreviations and pinyin, and tolerates misspellings. Returns the definition, the term in the other language, close matches and links.
trading
get_trading_system_rules
Without id: lists Clear Tape's eleven preset trading systems (trend, breakout, momentum and volume) with their style, holding period and one-line entry, stop and exit. With id: one system's exact written rules (entry, stop, exit, target, parameters, the data it needs, terms, where it differs from the published method), its strengths, weaknesses, who it suits and its sources, worded exactly as on its strategy page. Rules only: no signals, no prices, no performance figures. Educational, not investment advice.

How MCP servers expose tools in the first place →
Is Clear Tape working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 211 ms. The bar chart above shows every period we have measured.
How do I connect Clear Tape?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Clear Tape need an API key?
No. Clear Tape completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Clear Tape?
It answers our handshake in 211 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
