Help with MA cross over Price IN EA

New comment

I am attempting to create a simple EA that uses only the Close Price of the Previous bar compared to an MA of 'x' periods.

Parameters:

If the Close Price of the Previous bar is Higher than MA, then Buy.  Close the trade when the Close Price of the Previous bar is below the MA.


If the Close Price of the Previous bar is Lower than the MA, then Sell.  Close the trade when the Close Price of the Previous bar is above the MA.


So far, the Opening and Closing of the Trades is happening at the wrong times.  I cannot tell why.  I suspect it has something to do with my MA creation.


Any help is appreciated.


Thank you


The following is my code:

#property description "First, check to see if there is an open Trade."
#property description "If price is Higher than MA, then Buy; "
#property description "Close the trade when the price is Lower than the MA."
#property description "If price is Lower than MA, then Sell; "
#property description "Close the trade when the price is Higher than the MA."

What is the index of "previous bar" ?

What is the index of "previous bar" ?
I have it set to One in the 'Close' array.

  The original post showed it set to zero because I had been playing with the numbers to understand what was happening.  Forgot to set it back before posting.  Sorry for confusion, I made an edit to correct it.

Hi Randy. Any idea why I get this error when trying to compile the MT5 script in this thread. Regards. Wayne

wayneae #: Any idea why I get this error when trying to compile the MT5 script in this thread. Regards. Wayne

  1. Because zero is not one of the ENUM_TRADE_REQUEST_ACTIONS ; exactly what the message says.

  2. Because you are calling OrderSend and not checking its return code; exactly what the message says.

    Check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler (MT5/MT4+strict), it is trying to help you.
