Chuck,
yes I seen this .... I forgot to add something. If no sell is found in the j-loop you have to set i to BarCount. At least this is what I think you mean. Here is the adjusted version below that I think solves this problem. But like Tomasz mentioned one also can use ApllyStop for this. The version below gives the exact same result as when you use the ApplyStop function.
Let me know if this works and this solves the problem that you meant
rgds, Ed
procedure sell_proc(Buy,BuyPrice,open,high,low,close) {
global Sell;
global SellPrice;
global BuyAdjusted;
global exitLevel;
// initialise arrays
SellPrice = BuyPrice; SellPrice = 0;
Sell = SellPrice; exitLevel = Sell;
BuyAdjusted = Sell;
exitLevel[ 0 ] = buyPrice[ 0 ];
for (i = 1; i < BarCount; i++) {
exitLevel[ i ] = exitLevel[ i - 1 ];
//
if (Buy[ i ] == 1) {
BuyAdjusted[ i ] = 1;
exitLevel[ i ] = BuyPrice[ i ];
// find a sell position + sellprice
for (j = i; j < BarCount; j++) {
exitLevel[ j ] = exitLevel[ i ];
// test if profit stop is hit
if (Close[ j ] > exitLevel[ i ]) {
Sell[ j ] = 1;
SellPrice[ j ] = Close[ j ];
// enter i-loop past the last sell
i = j;
// escape from j-loop
j = BarCount;
} else if (j == BarCount - 1) {
i = BarCount;
}
}
}
}
} // end procedure
SetBarsRequired(10000,10000);
Buy = C < BBandBot(C, 10, 2);
BuyPrice = Open;
sell_proc(Ref(Buy,-1),BuyPrice,open,high,low,close);
Buy = BuyAdjusted;
SellPrice = Close;

Subject: RE: [amibroker] Help with entry price? (for Ed)
Ed,
Thanks so much for taking the time to work on this for me. I've been
working with it for several hours and I still have one problem that I can't
solve.
Refreshing your memory as to what this system does:
a. It buys at the open tomorrow if the close today is below some bollinger
band level.
b. It sells at the first profitable close.
The problem arises when there is a fresh "buy" signal prior to getting a
sell. It nicely ignores the buy signal, since it is already long, but it
establishes a new entry price based on the "buy" signal that is ignoring.
I'm stumped.
Any ideas?
Thanks

here is the version that uses loopings instead of ApplyStop,
rgds, Ed
procedure sell_proc(Buy,BuyPrice,open,high,low,close) {
global Sell;
global SellPrice;
global BuyAdjusted;
global exitLevel;
// initialise arrays
SellPrice = BuyPrice; SellPrice = 0;
Sell = SellPrice; exitLevel = Sell;
BuyAdjusted = Sell;
exitLevel[ 0 ] = buyPrice[ 0 ];
for (i = 1; i < BarCount; i++) {
exitLevel[ i ] = exitLevel[ i - 1 ];
//
if (Buy[ i ] == 1) {
BuyAdjusted[ i ] = 1;
exitLevel[ i ] = BuyPrice[ i ];
// find a sell position + sellprice
for (j = i; j < BarCount; j++) {
exitLevel[ j ] = exitLevel[ i ];
// test if profit stop is hit
if (Close[ j ] > exitLevel[ i ]) {
Sell[ j ] = 1;
SellPrice[ j ] = Close[ j ];
// enter i-loop past the last sell
i = j;
// escape from j-loop
j = BarCount;
}
}
}
}
} // end procedure
SetBarsRequired(10000,10000);
Buy = C < BBandBot(C, 10, 2);
BuyPrice = Open;
sell_proc(Ref(Buy,-1),BuyPrice,open,high,low,close);
Buy = BuyAdjusted;
SellPrice = Close;
Plot(C,"C",1,64);
Plot(exitLevel,"",colorWhite,1);
Plot(BBandBot(C, 10, 2),"",colorLightBlue,1);
PlotShapes(IIf(Buy,shapeUpArrow,0),colorWhite, layer = 0, yposition =
BuyPrice, offset = 0 );
PlotShapes(IIF(Sell,shapeDownArrow,0),colorYellow, layer = 0, yposition =
SellPrice, offset = 0 );

Hello,

This can be successfully achieved using ApplyStop (profit target stop)
with mode set to point and profit set to small value (0.001)
Best regards,
