If you want to do what you are proposing, you don't need CBT.
Whenever you recognize a "scalein" condition, just set the BuyPrice to the average of buyprice1 and buyprice2, and the position size to double the usual size. The backtester exits all positions (initial and scaled in) at a single Sell signal, so that is effectively what is happening anyway.

XYZ starts the day at $10 and I want to buy if it loses 1% and scalein to double to position if it loses another 1%. Is there a way to code for that to occur on the same bar assuming XYZ traded below $9.80 on the bar in question? I know how to do it with Scalein when it occurs on seperate bars?
