📌 Product Description
SP500 EMA EA with Smart TSL & RSI
A professional, fully automated Expert Advisor designed specifically for high-precision SP500 index trading.
Built by Peter Dimitrov, this EA combines a reliable EMA crossover system, dynamic risk-based position sizing, RSI filtering, advanced smart trailing stop logic, and fully configurable trading sessions.
🔍 Strategy Overview
This Expert Advisor uses a robust trend-following logic based on the crossover of two EMAs (21 & 200 by default), combined with RSI filtering to avoid entering during overextended market conditions.
When a valid signal appears, the EA calculates the recent market low, determines an adaptive stop-loss distance, and automatically adjusts the lot size based on the trader’s Max Risk % setting. This ensures controlled and consistent risk management on every trade.
The integrated Smart Trailing Stop (TSL) mechanism dynamically follows price peaks and adjusts the stop-loss only when the conditions are optimal—ensuring trend trades are protected without reducing profit potential.
📈 Recommended Symbol & Timeframe
Symbol: SP500 / US500 / S&P 500 CFDs or futures
Timeframe: M30 (default)
Account Types: ECN, Raw Spread, low-spread accounts recommended
