Specification

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.
  • 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).
Position sizing choices (selectable by user):
  • 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.
Risk & profit management features:
  • 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)
Trading hours restriction (optional):
  • 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.
Other important points:
  • 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
Before moving forward I will share the indicator file(s). What I expect in your offer:
  • 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
Looking forward to serious proposals only. Thank you.
