Trend Buy/Sell Zones with Automated Lot Sizing and Risk Panel for MT5

Related: ADX Auto Range: Automated Trend Strength and Consolidation Detection - another powerful indicator for MetaTrader 5 traders.

AlgoFX is a trend-following indicator for MetaTrader 5.

Also recommended: Line Master: Advanced Trend Lines with Change Signals - similar indicator with strong performance on MetaTrader 5.

It identifies potential areas where price may retrace within an established trend, highlighting zones where buyers or sellers might re-enter the market.
While developed with Gold (XAUUSD) in mind, it is adaptable to any trading instrument and timeframe.

AlgoFX serves as an analytical tool, indicating potential zones rather than providing direct entry, stop loss, or take profit signals.



HOW IT WORKS



Trend Identification

- The trend is determined by the 50-period Exponential Moving Average (EMA) and the 200-period EMA.

- An uptrend is confirmed when the EMA 50 is above the EMA 200 and the EMA 200 is rising.

- A downtrend is confirmed when the EMA 50 is below the EMA 200 and the EMA 200 is falling.

- If neither condition is met, the indicator signals "No clear trend" on the panel.



Potential BUY Zone (Uptrend Only)

- This zone is identified when the price retraces to an area just below the EMA 50, with the depth defined by the Average True Range (ATR).

- A bullish candle that closes above the zone confirms its validity.

- The zone is visually marked with a green box and an arrow, labeled "Potential BUY zone".



Potential SELL Zone (Downtrend Only)

- This is the inverse of the BUY zone.
- Price rallies into an area just above the EMA 50, and a bearish candle closes within the zone.

- The zone is marked with a red box and an arrow, labeled "Potential SELL zone".



Additional Filters

- Optional RSI Filter: Prevents BUY zones when the RSI is overbought and SELL zones when the RSI is oversold.

- Cooldown Period: Ensures a minimum number of bars between zones on the same side to prevent visual clutter.



No Repainting

- Zones are calculated exclusively on closed candles.
- Once a zone appears, it remains fixed and does not change or disappear, ensuring historical accuracy.



RISK PANEL

The on-chart panel provides the following information:

- Current trend status.

- Account balance or equity (user selectable).

- Risk per trade, displayed as a percentage and in account currency.

- Suggested lot size, automatically calculated based on user-defined risk percentage, ATR-based stop distance, and the symbol's tick value.

- Today's profit or loss across the entire account.

- A warning alert when the daily loss limit is approached or reached.



The lot size calculation is designed to never exceed the defined risk. It also adheres to the broker's specifications for minimum lot size, maximum lot size, and lot step increments.
If the calculated risk is too small to accommodate the minimum lot size, the panel will indicate this instead of suggesting a larger, unsuitable trade.
