I am trying to learn IB API interface and test and modify some of my strategies. I can download historical data through Excel DDE in IB. I also use scale trader in TWS for my trades. Now my question is how I can feed the loaded data to the existing scaletrader in IB for backtesting? If yes, how? Is there any tutorial on how to do it? Should I also write my own scale trader program? I know it is a basic question for those who constantly use API and backtest theor system.
