Universal MT5 Expert Advisor – Opening Level Intraday Strategy (M15, All Indices)

Description:

I’m looking for an experienced MQL5 developer to build a flexible and universal Expert Advisor (EA) for MetaTrader 5. The EA should implement a time-based, price-action strategy that works across multiple indices like S&P500, DAX, NASDAQ100, Nikkei225, etc.

Strategy Summary:

• Asset class: Index CFDs or Futures (symbols like US500, NAS100, DE40, JP225 – varies by broker)

• Timeframe: M15

• Trade types: Long and Short

• Strategy: Intraday only, based on price behavior relative to the daily Opening Level

• No indicators – purely based on candle closing logic

Entry Rules:

• The first full M15 candle after market open defines the Opening Level.

• Long entry: if any following M15 candle closes above the Opening Level → enter long at candle close.

• Short entry: if any following M15 candle closes below the Opening Level → enter short at candle close.

• If the first candle is a Doji, skip it. Wait for the next valid signal.

• Session times vary per instrument. The user must be able to configure:

  • Session start time

  • Last valid entry time

  • Forced exit time

Trade Management:

• If a trade is active and a new opposite signal appears → close the trade and reverse direction.

• Re-entries in the same direction are allowed only if the candle body confirms the trend.

• No new entries allowed after the defined cutoff time.

• All trades must be closed by a user-defined session end time – no trades are held overnight.

Stop Loss / Take Profit / Break-Even:

• Stop Loss:

  • Long: below the signal candle’s low

  • Short: above the signal candle’s high

• Take Profit: equal distance as SL (1:1 RRR)

• Break-Even: once price moves 50% of the way to TP, SL is moved to breakeven

Risk Management:

• User must be able to define account risk per trade in % (e.g. 1.0%)

• EA must calculate position size dynamically based on:

  • Account balance

  • SL distance

  • Selected risk percentage

Required Inputs:

• RiskPercent

• SessionStartTime

• LastEntryTime

• ForceExitTime

• BreakEvenEnabled (true/false)

• MagicNumber

• TradeComment

Additional Requirements:

• EA must work with any index symbol and any broker (handle suffixes/prefixes like .cash or .i)

• Time calculations should be based on server/broker time

• Strategy must be 100% rule-based, with clean execution and stable order handling

• EA must support strategy tester and live use without manual adjustments

Deliverables:

• Source code (.mq5) and compiled file (.ex5)

• Basic parameter documentation

• Error handling and internal checks for stability

Please apply only if you have experience with time-based or candle-logic-based EAs. Send samples of your work if available. I'm ready to start as soon as possible.
