Reversal Expert Advisor Drawing
Reversal Expert Advisor Drawing
The attached VTS system is a single-drawing that implements a reversal system.
It uses the function fnGetOpenOrderInfo twice:
- once get the number of open orders (MyTotal)
- once to get the type of open order (MyOrderType)
It uses 2 Logics
- one to set the order type (OP_SELL or OP_BUY) if an order is open (AreThereAnyOpenTrades)
- one to open a trade if none are opened, a SELL if the last trade (held in _MyOrderType) was a BUY, or vice-versa
Notice I try to give the names of each Element a descriptive name.
Notes:
- The MetaTrader MQL built-in variables for order types are OP_SELL and OP_BUY.
- In VTS, when you create a function that returns a value, a variable is automatically created to hold the value with the same name as the function with a preceding underscore.
This logic is a little tricky, I may add a function to VTS to automatically run a reversal.
I’ll add a video to this post shortly.
