[amibroker] Buy and ScaleOut on same bar

[dralexchambers]

Hello - I am having trouble working out how to enter and scale out on 
the same bar:

This code enters my position:

if (entrybar[i]==1)
{
   Buy[i] = 1;
   BuyPrice[i] = O[i];
}

This code exits at a 5 point profit on the same bar:

if (entrybar[i]==1)
{
   Buy[i] = sigScaleOut;
   BuyPrice[i] = O[i] + 5;    // ie. 5 points from my original 
buyprice
}


However, this isn't working in the backtester. 

Can anyone advise on the correct code to do this please - thanks!
