Indicator Trader EA
v1.0 for MetaTrader 5
Universal EA that bridges any custom indicator's signals to automated trading
XAUUSD · Major Forex Pairs · Crypto ｜ All Timeframes M1 ~ D1
📌 Overview
Indicator Trader EA is a universal Expert Advisor that automatically executes buy and sell orders based on signal buffers from any custom indicator.
With a single EA, you can connect any commercial indicator (SuperScalp Pro, Trend 7Filter Pro, etc.) directly — no extra coding required. Simply configure the buffer indices and you have a fully automated trading system.
✨ Key Features
▸ Dual load modes: Direct Load (Mode A) / Chart Instance Auto-Detect (Mode B)
▸ Indicator buffer-based SL/TP automatic configuration
▸ ATR-based dynamic TP/SL and trailing stop
▸ Dollar-based group P&L close (Group TP/SL)
▸ Automatic position flip on opposite signal
▸ Duplicate order prevention per bar (OncePerBar)
▸ Maximum position limit (MaxPositions)
▸ Real-time Alert notifications
▸ Debug mode for live signal buffer inspection
🎯 Who Is This For?
▸ Traders who want to automate signals from commercial indicators
▸ Developers who want to add auto-order functionality to custom indicators
▸ Compatible with any symbol: XAUUSD, forex pairs, crypto, and more
⚙️ How It Works
On every tick, the EA reads the indicator's signal buffers and detects valid signals (any value other than 0 or EMPTY_VALUE).
Signal Detection Logic
▸ bar[1] confirmed signal: processed at the start of each new candle — most reliable
▸ bar[0] real-time signal: processed as the current bar forms — faster reaction
▸ Duplicate prevention: when OncePerBar=true, only one order per direction per candle
Order Execution Flow
Signal detected → Check CloseOnOppositeSignal → Close opposite positions
→ Verify CanOpenBuy/Sell() conditions → Execute OpenOrder()
→ Set SL/TP (indicator buffer OR ATR OR dollar-based)
→ Every tick: Group P&L monitoring when UseGroupClose=true
📖 How to Use
Mode A — Direct Load (Recommended)
The EA loads the indicator automatically — no need to add it to the chart separately.
IndicatorName = "Market\SuperScalp Pro" ← MQL5 Market product
IndicatorName = "Trend 7Filter Pro" ← File in Indicators folder
IndicatorName = "MyFolder\MyIndicator" ← Subfolder path
Mode B — Chart Instance Auto-Detect
Apply the indicator to the chart first, then attach the EA. It will automatically detect the running indicator instance.
IndicatorName = "" ← Leave blank
▸ Recommended when only one indicator is applied to the chart
▸ Use when you need to apply custom parameters to the indicator
How to Find Buffer Indices
You need to identify the buy/sell signal buffer indices of your target indicator.
▸ Set DebugMode = true and attach the EA
▸ Check the MetaTrader Journal tab for buffer values
▸ Refer to SetIndexBuffer() order in the indicator's source code

⚠️ Important Notes
▸ Always verify your indicator's signal buffer indices and set BuyBuffer/SellBuffer correctly.
▸ When UseGroupClose=false, only server-side SL/TP per order is active — trailing stop is disabled.
▸ In Mode B, the indicator must be applied to the chart before attaching the EA.
▸ Always test thoroughly on a demo account before live trading.
▸ Past performance does not guarantee future results.
