Why is my EA not moving my position to breakeven?

问题

I'm attempting to modify my market orders to breakeven the position when the position get 100 pips to the good. This also accounts for the StopLevels which are around 20-30 pips for my broker. It checks the param's via a "for(){...} loop" function

The MagicNumber is the timeframe number for the chart it is on (i.e. 240=4H, 60=1H) I don't set a TakeProfit price & initially no StopLoss price.

The EA is not adding a SL to be equal to the opening price when the trade reaches 100 pip in profit (plus stoplevels). Profit points reaches well over 130 points.

My code is below for a OP_SELL order - any help would be appreciated. Regards, Todd

For the moment being,
refine the code
and
add self-debuging / tracing code

After OrderModify() use a self-debugging / journaling Print( StringFormat( ... ) ) to document all instructed values used in the actual OrderModify() call and also the remote-execution ( { server-side | StrategyTester } ) reported issues.

The current code does not enter into such self-diagnostics and ModSell is not inspected at all, ModBuy is inspected only at uncertain conditions / by-coincidence at some future visit of the for(){...} code-execution path to a part after newSL == sl ( and all above stated conditions are just by chance met too )

Next, check an assigned value of `tp`

As stated above,

/*Local  Declarations*/
...
tp                   =  OrderTakeProfit();

which introduces a reasonable doubt, that re-using of this ( inherently uncertain value, as no one knows, which OrderSelect() was the last one that set a db.Pool pointer to decide, from which record from the db.Pool this veryOrderTakeProfit() would accidentally read ( if any record is present in db.Pool already ) inside the whole for(){...} traversing the db.Pool records will not meet conditions for setting properly a TakeProfit price in the next series of OrderModify() calls.

This seems to be the root cause, or a source of unhandled exceptions to the valid, Broker-compliant, OrderModify() values.

Try this:

if (newSL != sl ) {
    ModSell = OrderModify( OrderTicket(),
                           OrderOpenPrice(),
                           OrderOpenPrice(),
                           0,
                           OrderExpiration(),
                           clrRed
                          );
    if(ModBuy == false )
        Print( "OrderModify failed with error #", GetLastError());
}

Then check the Expert-tab for error-message if it fails to set the stop.

Also, you need to take note that StopLoss will ONLY occur if you are on the right chart-timeframe; Otherwise, it won't even get into the if-statements.
