Hi romolusne,
Once you hash out the two lines you need to compile the code. Once the code is compiled those strategies will not trade again. From the screenshot provided the only two strategies that can still be trading are strategies 004 and 007. To stop these from trading you need to hash out lines 783,784,795, and 796. Once these are hashed out and the code is compiled they will no long be able to trade.
Alan,
