Prop-Firm Ready EA for US Indices (NAS100, US30, SP500) based on EMA Crossover

Hello,

I am looking for an experienced MQL5 developer to develop a custom Expert Advisor (EA) for MetaTrader 5, designed to trade NAS100, US30 and SP500, with strict Prop Firm risk management, specifically compatible with FundedNext rules.

1. Trading Strategy – EMA Crossover

The EA must monitor EMA indicators on M5 and M15.

Inputs:

• Fast_EMA_Period (default: 9)
• Slow_EMA_Period (default: 50)

BUY: Fast EMA crosses above Slow EMA.
SELL: Fast EMA crosses below Slow EMA.

Optional input to immediately close the current position when an opposite crossover occurs before SL or TP is reached.

2. Risk Management

• Risk_Percent – dynamic lot calculation based on account balance/equity and SL distance. Default: 0.2% per trade.
• Stop_Loss_Points – hard SL sent with the market order.
• Take_Profit_Points – hard TP sent with the market order.
• Enable_Breakeven – enable/disable Breakeven.
• Breakeven_Trigger_Points – points required to move SL to entry.
• Enable_Trailing – enable/disable trailing stop.
• Trailing_Stop_Points
• Trailing_Step_Points

SL/TP must be placed directly with the order; no hidden or mental stops.

3. Prop Firm Daily Drawdown Protection

Max_Daily_Loss_Percent – default 2.5%.

If the account reaches the configured daily drawdown limit, including floating loss, the EA must:

1. Immediately close all EA-managed open positions.
2. Delete EA-managed pending orders.
3. Disable trading completely.
4. Remain disabled until the next trading day.

Max_Open_Trades – maximum simultaneous positions, default 1.

The daily protection must remain valid after EA/MT5 restart and must not reset incorrectly.

4. Market & Time Filters

• Max_Spread_Points – prevent new entries when spread exceeds the configured limit.
• Trading_Window_Start
• Trading_Window_End

Trading hours must be configurable using Broker/Server Time.

5. News Filter

Inputs:

• News_Filter
• Minutes_Before_News
• Minutes_After_News

The EA should use the MT5 Economic Calendar to detect high-impact (3-star) news.

During the configured protection window, the EA must stop trading and prevent new entries.

6. Technical Requirements

• Magic_Number – unique identifier for EA-managed trades.
• Instrument_Suffix – support broker-specific symbols such as NAS100.sb , USTEC , etc.
• Correct handling of broker specifications, lot size, tick value and tick size.
• Fast execution and low latency.
• Proper handling of requotes, slippage, invalid stops, insufficient margin and trading errors.
• The EA must not interfere with trades belonging to other EAs or manual trades.

7. Delivery

Please provide:

• Complete and clean MQL5 source code ( .mq5 ), fully commented.
• Compiled .ex5 file.
• Error-free compilation.
• Testing in MT5 Strategy Tester before delivery.

Only developers with proven experience developing Prop Firm EAs should apply.

Please include in your proposal:

• Total price.
• Estimated delivery time.
• Relevant previous MQL5/Prop Firm projects.
• Experience with daily drawdown protection and MT5 Economic Calendar.
• Any technical questions or limitations you identify.

Thank you.
