MT5 EA — for prop firm traders
Lotsmith is the discipline layer your funded account is missing. Position sizing, drawdown guards, anti-revenge cooldown, multi-TP execution, and prop-firm rule presets that auto-update when firms change rules.
Built for traders challenging
Most funded accounts blow up not from a bad strategy, but from broken discipline mid-trade. Lotsmith makes those mistakes impossible.
Risk %, SL distance, 1–4 take-profits — Lotsmith opens N independent legs sharing one stop. Lot rounded to broker step, validated against StopsLevel.
Hard-block trades that would breach your prop-firm DD. Live counter on the panel: "Daily left $4660 — Max left $10340".
Pick FTMO Challenge, FundedNext Stellar, E8 One, etc. — every parameter is auto-configured. When firms change rules, EA picks up the update within 6 hours. No reinstall.
When price reaches your BE trigger, SL on every leg moves to entry — instantly. Optional trail-after-BE protects winners as they run.
After N consecutive losses, the panel locks for X minutes. No "I'll just take one more to get it back" trade. Killer feature no competitor has.
Hit +2% today? Lotsmith closes everything and locks the panel until tomorrow. Stops you from giving back profit. Optional, off by default.
Spread filter, per-symbol cap, total cap, symbol whitelist, daily setup limit, daily-loss kill-switch, time/day window, exposure cap. Each click checks all rules — first violation wins, with a clear reason.
Open / close / TP hit / SL hit / DD warning / cooldown / daily target — formatted with risk + remaining DD. Configure once, glance at your phone instead of staring at MT5.
One .ex5 file. Works on Windows native, Mac via broker-bundled Wine, and any VPS. No installer, no service, no driver.
License-key auth only. We never see your broker password, your positions, or your equity. Optional discipline leaderboard is opt-in with a pseudonym.
Five minutes from purchase to a guarded trade.
Receive your license key by email instantly.

A $500 evaluation fee buys you one shot at a $100K account. Lotsmith costs less than $20/month and is the difference between making it through Phase 1 and starting over.
No. Lotsmith is a discretionary trading aid — you click BUY/SELL yourself. It doesn't run autonomous strategies, it doesn't HFT-scalp, and it doesn't copy from other traders. Almost every prop firm allows manual EAs that assist position sizing and risk management.
We update the preset on our server. Your EA refetches every 6 hours (or instantly on chart reload) and applies the new values. No reinstall, no recompile. This is the main reason Lotsmith is a subscription instead of a one-time purchase.
Yes. MT5 doesn't have a native Mac build, but every major broker (FTMO, IC Markets, Pepperstone, Exness…) ships a Wine-wrapped MT5 .pkg/.dmg for macOS. Lotsmith is a single .ex5 file — it runs identically wherever MT5 runs.
Yes. The Standard plan covers one active MT5 terminal — that can be on a VPS, your laptop, or wherever you trade. Pro covers up to five.
Your license key + the timestamp of each preset fetch, for fraud detection. We never see your broker credentials, balance, equity, or trades. The optional discipline leaderboard is fully opt-in and uses a pseudonym you choose.
Lotsmith keeps running with the last cached preset, so you never lose access mid-trade. New preset updates stop until you renew. 30-day money-back if Lotsmith didn't help — just email support.
