Техническое задание
I need a reliable, clean-coded Expert Advisor built for both MetaTrader 4 and MetaTrader 5 platforms.Main trading behavior:
The EA follows buy and sell arrows produced by my custom indicator.
The EA follows buy and sell arrows produced by my custom indicator.
- Whenever a buy arrow shows up on the chart: if a sell position is currently open → close that sell immediately and enter a buy trade in its place.
- Whenever a sell arrow appears: if a buy position exists → close the buy and switch to a sell trade.
In short: the system always flips direction when the opposite signal arrives (one active trade direction at a time).
- Option A: Fixed volume – preset to 0.01 lots, changeable in the settings.
- Option B: Automatic volume growth – begins at 0.01 lots and adds 0.01 lots to the size for every full 100 units of realized account profit (in account currency). Example: after +100 profit → 0.02 lots; after +200 → 0.03 lots, and so on.
- Take-profit distance (pips) – adjustable, can be turned off
- Stop-loss distance (pips) – adjustable, can be turned off
- Trailing-stop system (on/off switch included):
• Activation level (pips in profit before trailing begins)
• Step size (pips the price must move to pull the stop again)
• Trailing distance (pips behind current price)
- Earliest allowed entry time (hour : minute, server time)
- Latest allowed entry time (hour : minute, server time)
New trades are blocked outside this window, but open trades continue to be managed normally.
- Assign a magic number so the EA only touches its own orders
- Include basic spread check (max spread input) and clear error messages
- Well-commented code + sensible default values and tooltips in inputs
- Structure the code so 2–3 extra indicators can be added later for signal filtering or confirmation without major rewriting
- Total fixed price for both MT4 + MT5 versions
- How many days you estimate it will take
- Yes/No confirmation that future indicator additions are realistic with your approach
- Brief note about your experience with similar reversal / arrow / trailing EAs
- Link(s) to previous relevant work if available
