prop-firm-rules: prop firm drawdown rules dataset + calculator (JS & Python)
Free, sourced prop-firm drawdown rules for traders and AI agents: dataset, JS/Python calculator, REST API and a no-auth MCP server.
MCP (Claude, Cursor, any MCP client), no key needed:

"mcpServers": {
"prop-firm-rules": {

Prefer to run it yourself? The repo ships a zero-dependency stdio server (mcp/server.mjs, Node 18+, works offline on the
bundled dataset): {"mcpServers": {"prop-firm-rules": {"command": "npx", "args": ["-y", "github:kburrus64-max/prop-firm-rules"]}}}
▶ Live calculator (free, no sign-up, runs in your browser): floorguard-kappa.vercel.app/tools/drawdown-calculator.html
An open, sourced dataset of prop-firm risk rules (daily loss limit, max drawdown, static vs trailing, lock level,
daily reset time) for FTMO, FundedNext, The5ers, E8 Markets, FundingPips, Alpha Capital, Blue Guardian, Topstep and
Apex Trader Funding, plus a tiny zero-dependency drawdown calculator library in JavaScript and Python.
Every rule links to the firm's own help or rules page and carries a lastVerified date. Values that could not be
confirmed on an official page are flagged verified: false or listed in unverifiedFields.
Try it without code: the free prop firm drawdown calculator
on FloorGuard uses this same dataset and math in your browser.
Disclaimer: rules change. Prop firms update their rules often, and many let you pick different percentages
at checkout. This data was checked on the date shown for each program. Always verify with your firm's current
rules and your account dashboard before relying on any number here. Not affiliated with any prop firm; firm
names are trademarks of their owners. Not financial advice.

"Day-start" means the value at the firm's daily reset. "Higher of day-start balance/equity" means open profit at the
reset raises the reference. Every limit is checked against equity (open P/L counts) unless the notes say otherwise.
Per-program notes (for example Topstep's optional daily loss limit, Apex lock behaviour, Blue Guardian's Guardian
Shield) are in data/firms.json.
The dataset also includes each firm's published copy-trading, multi-account and automation (EA/bot) policy
(policy on each firm), with quotes and sources. unknown means the firm's pages did not answer the question.
What's in the repo
Usage
JavaScript (Node 18+)
git clone https://github.com/kburrus64-max/prop-firm-rules && cd prop-firm-rules
node --test js/test/
import { check, getFirm } from './js/index.mjs';
const r = check('ftmo_2step', {
size: 100000, currentBalance: 102000, currentEquity: 101200, todayPnl: -800,
stopDistance: 20, valuePerUnit: 10, bufferPct: 10,
});
console.log(r.daily.floor, r.daily.room);
console.log(r.drawdown.floor);
console.log(r.maxLots, r.bindingLimit, r.status);
console.log(getFirm('topstep').policy.remoteServerTrading);
In the browser, import js/calc.mjs and fetch data/firms.json:
import { evaluate } from './calc.mjs';
const data = await (await fetch('/data/firms.json')).json();
const program = data.firms.find(f => f.id === 'topstep').programs[0];
evaluate({ program, size: 50000, currentBalance: 50000, currentEquity: 50000, highWaterMark: 50500 }).drawdown.floor;
Python 3.9+
import sys; sys.path.insert(0, "python")
import prop_firm_rules as pfr
r = pfr.check("apex_intraday_eval", size=50000, current_balance=50000, current_equity=50900, today_pnl=900)
print(r["drawdown"]["floor"])
python -m unittest discover -s python/tests
| Input | Meaning |
|---|
program / program id | A program object from the dataset (or an id for check) |
size, initial | Account size and starting balance (initial defaults to size) |
currentBalance, currentEquity | Now. The lower of the two is compared with each floor (conservative) |
todayPnl | Change in equity since the firm's daily reset (closed + open) |
dayStartBalance, dayStartEquity | Values at the reset (optional; derived from todayPnl if omitted) |
highWaterMark | The high a trailing drawdown trails from (EOD balance, closed balance, or intraday peak) |
customDailyAmount | Your own daily limit for programs without a mandatory one (e.g. Topstep's optional add-on) |
stopDistance, valuePerUnit, lotStep, bufferPct | Position-size check: largest size whose stop-out keeps you above the tighter floor |
Output: daily and drawdown (floor, room, amount, status), maxLots, bindingLimit and an overall
status of green (more than 50% of each allowance left), amber (50% or less) or red (20% or less, or breached).
Python uses the same names in snake_case (current_balance, high_water_mark, ...).

node mcp/server.mjs. Same three tools and the same math as the hosted endpoint.

Static vs trailing drawdown in 30 seconds
- Static: the floor is fixed at initial balance minus the allowance (FTMO 2-Step: $90,000 on $100k).
- Trailing end-of-day: the floor follows your highest end-of-day balance (Topstep MLL, FTMO 1-Step, Apex EOD).
- Trailing closed balance: follows your highest closed balance (E8 dynamic drawdown).
- Trailing intraday: follows your peak including open profit, in real time (Apex intraday).
- Lock: some trailing floors stop rising at a level such as the starting balance (Topstep, E8).
Longer explanations with sources: trailing vs static drawdown,
FTMO daily loss rule,
same 5% daily loss, different math.

Limitations
- Commissions, swaps, slippage and server-side rounding are not modelled; firms' platforms can differ by a few dollars.
- Account-size lists marked
sizesVerified: false were not confirmed on an official page.
- Programs with features this model does not cover (e.g. Blue Guardian funded-account Guardian Shield, consistency rules,
news restrictions, payout rules) are noted in
notes but not calculated.
