Re: [amibroker] A question regarding ApplyStop in NBars

[Graham <kavemanperth@xxxxxxxxx>]

It depends on the Buy conditions. If this can have signals within the
LExitDays bars then your Sell=Ref(Buy, -LExitDays) ; will reset for
each new buy signal. The exrem does not appear until afterwards so has
no effect. The 2 methods would be to either use exrempsan, or Equity

Buy= ExRemSpan(Buy, LExitDays);
Sell=0;
ApplyStop(stopTypeNBar, stopModeBars, LExitDays, True, False );

or


Sell=0;
ApplyStop(stopTypeNBar, stopModeBars, LExitDays, True, False );
Equity(1,0);

the use of equity also allows for you to plot the sell on the chart
using plotshapes as it assigns a number to the sell array depending on
which type of applystop is used
PlotShapes( shapeDownArrow*(Sell>0), colorRed, 0, H, -10 );
