MQL5 port of a Pine Script ATR trailing-stop indicator: nLoss = ATR-multiple, the stop ratchets under price in an uptrend and over price in a downtrend, and flips (with a buy/sell arrow) when price closes through it. Includes a Python reference port and a parity test that checks both agree with a literal, bar-by-bar transcription of the Pine semantics (na/nz/series history).

Protect Your Funded Account with Institutional-Grade Risk Monitoring. The #1 reason traders fail prop firm challenges is not a bad strategy; it is breaching daily drawdown limits. The AlphaQuant Prop Firm Daily Drawdown Dashboard is a free, high-visibility Expert Advisor

TREND Follower (Daily) is a lightweight, development-oriented Expert Advisor (EA) created as a base trading architecture for research, learning, experimentation, and further development. The EA is intentionally designed around a simple concept: follow the market direction using the relationship between price and the Parabolic SAR. It is not presented as a fully optimized or finished trading system. Instead, it provides a clean and accessible foundation that developers can study, modify, test, and expand.

Account-wide MT5 risk protection EA for prop-firm and personal accounts. Monitors daily and overall drawdown, position losses, safety buffers, and automatically protects the account when configured limits are reached.

Spread histogram in a sub-window with current/avg/max/min stats, cost per trade, and threshold alerts for scalpers.

Numbers every candle of the current trading day starting at the cash open of Frankfurt, London, New York or Tokyo. The anchor is converted from exchange local time to broker server time with automatic daylight saving, so the first candle after the open is always number one, in summer and in winter.

Professional Utility EA for prop firm risk management. It features daily equity monitoring, phased mitigation of losing positions, and absolute hard stops via a self-healing graphical dashboard.

Works out the lot from your risk percent and the stop distance, then opens the trade with the stop loss and take profit already attached. Never trades by itself.

Classifies the market with ADX, the Hurst exponent and lag-1 autocorrelation, routes each bar to a breakout module or a mean-reversion module, and keeps a separate win rate ledger for each regime with a Wilson 95% lower bound, so you can see which half of it is actually working.

Scores every setup type in your EA on its own record instead of lumping them into one equity curve. Rebuilds itself from the account's deal history on init so a restart cannot wipe the record. Prints a Wilson score lower bound next to the raw win rate so a three trade hot streak stops looking like an edge.

Position size from a risk amount, computed from the symbol's real tick value, tick size and volume step rather than an assumed pip value. It always rounds volume down, and when your risk is smaller than the minimum lot it says so and reports what that lot actually costs. No terminal state, so the sizing logic is testable offline - a 41-assertion test script is included.

Heiken Ashi ATR Blend combines smoothed Heiken Ashi candles, ATR-based volatility filtering, and fast/slow EMA trend confirmation to identify potential trend-change signals.

Closes losing positions early, before the full stop-loss, when a rule says the trade is not coming back: adverse move beyond N x ATR, too long in loss, EMA trend flipped, RSI against the position, or a money cap. Never touches a position in profit. Observe-only mode journals what would be closed without closing anything. Every exit is written to CSV with the rule, the age and the maximum adverse excursion, so the rules can be tuned from data.

Enforces your own risk rules on every position, whether opened by hand or by another EA: shows the lot size that matches your risk, locks the account for the day after a set loss, caps open positions, trims positions that risk more than allowed, and adds a stop-loss to any position opened without one.

Strict risk management utility for prop-firm challenges. Automatically monitors your entire account to prevent daily and max drawdown failures. It acts as a safety buffer against spread spikes and revenge trading by instantly closing all positions and pending orders before your evaluation is terminated.

Free MT5 position risk monitor displaying stop-loss risk, account risk percentage, positions without SL and individual position risk directly on the chart.

Free neon-style MT5 account dashboard displaying balance, equity, floating P/L, daily realized P/L, win rate and open positions directly on the chart.

GDS Renko Canvas + Donchian is a compact educational indicator for MetaTrader 5. It renders classic fixed-size Renko bricks on a single CCanvas bitmap layer and overlays a Donchian Channel calculated directly from completed Renko bricks. The horizontal axis represents Renko sequence rather than time. The internal builder uses incoming BID ticks and the classic two-brick reversal rule. The Donchian Channel is causal: for each newly completed brick, the channel is calculated from the previous N completed Renko bricks only. The current brick is excluded from its own channel calculation.
