hi,
this indeed can be done without using loops but if
you want to use loops it would look like (see also chart). But this can be done
without using loops,
rgds, ed
Buy = Cross(C,EMA(C,50));
Sell = 0;
BuyPrice = Open;
sellPricelevel = Null;
BuyAdjusted = 0;
for( i = 0; i
< BarCount; i++ )
{
if( Buy[ i ] )
{
BuyAdjusted[
i ] = 1;
sellPriceLevel[ i ] = BuyPrice[ i ] * 1.2;
for ( j = i + 1; j < BarCount; j++ )
{
sellPriceLevel[ j ] =
BuyPrice[ i ] *
1.2;
if (H[ j ] > sellPriceLevel[ j ])
{
Sell[ j ] = 1;
SellPrice[ j ] = Max(O[ j ],sellPriceLevel[ j ]);
i =
j;
break;
} else if (j == BarCount - 1) {
i =
BarCount;
}
}
}
}
Buy = BuyAdjusted;
SetBarsRequired(10000,10000);
SetChartOptions(0, chartShowDates);
Plot(C,"C",colorWhite,64);
PlotShapes(IIf(Buy,shapeUpTriangle,0),colorWhite, layer = 0,
yposition = BuyPrice, offset = 0 );
PlotShapes(IIf(Sell,shapeDownTriangle,0),colorOrange, layer =
0, yposition =
SellPrice, offset =
0 );
Plot(sellPriceLevel,"sell Level",colorBlue,styleThick);

Subject: [amibroker] Re: AFL looping
question!
Hi Ed, the loop is just a simple profit target stop for testing other
parts of my systems and a reference to the Entry Price.
Once
changing the "Close[ i ] > priceatbuy * 1.2" _expression_ and
basically
making it a stop, things go wrong. Or is it my logic? LOL
Am not too
familiar with looping and try to understand why this
doesn't
work.
Thanks

that
priceatbuy in the loop also needs to be handled as an element, like
priceatbuy[ i ], but then still I can't figure out what you are
trying
to do,
