Dynamic profit target help needed

[wallsteetking]

I have an issue with the profit target code

SetProfitTarget("", CalculationMode.Ticks, 4)

this works great when I have one position on. But when I have 4 positions, it sees every entry as unique, thus it only looks for 4 tick profit on a individual entry. How can I tell Ninjatrader to look for a 4 tick profit of the AVERAGE 4 positions I have active. for example

1 Position size:
Long : $1256 Profit target should be $1257

2 Position Size
Long $1250
Long $1210
AVG is $1230 profit target should be $1231

3 Position on
Long 1270
Long 1250
Long 1200
AVE is $1240 profit target now should be $1241

Long : 1254
Long : 1250
Long : 1210
Long : 1200

The average position size I have on is ~1228 so it should look for a profit target of 1229

So you are price-averaging down?

In that case, use CalculationMode.Price, and use the Position.AvgPrice as the target price.

SetProfitTarget("", CalculationMode.Price, Position.AvgPrice + 4 * TickSize);

Hey thanks this is what I was looking for...
I have one more question to ask you when I use this code

if (Position.GetProfitLoss(Close[0], PerformanceUnit.Currency) <= -200)

I noticed Ninjatrader will enter on every bar.. How can I tell ninjatrader to enter only ONCE on -200 loss???

Easiest way is to use a boolean flag, and check its state.

private bool CriticalFlag = false;

 
if (!CriticalFlag && Position.GetProfitLoss(Close[0], PerformanceUnit.Currency) <= -200)
{
// etc
CriticalFlag = true;
}
 
if (Position.MarketPosition == MarketPosition.Flat) CriticalFlag = false; //we need to reset this somewhere; either when Flat or at next entry.

I keep getting an error message. First when I put this code inside

protected override void Initialize()

SetProfitTarget("", CalculationMode.Price, Position.AvgPrice + 4 * TickSize);

I get this error message in the LOG TAP

4/29/2013 6:33:44 PM Strategy Failed to call method 'Initialize' for strategy 'A41/48f53ffd20a442cdb2d95d27e369e8bd': 'Position' property can't be accessed from within 'Initialize' method.

.

And when I put the code inside protected override void OnBarUpdate() I get this (see picture)

Logic error. You cannot possibly have a position in Initialize(): you cannot access that which you do not have.

And when I put the code inside protected override void OnBarUpdate() I get this (see picture)

It looks to me like you again have another logic error, where you called this statement before you were in a position, so this time the code just gave you an average price of zero, the only possibility for a non-existent position, other than to throw an exception. That puts your target at 4 ticks above zero, equal to $1.

The computer did what you told it. If what the 'puter did does not match your intent, then correct your logic.
