Not sure if you are stuck with 2Ki or not, but for the newer version of TS, The best way to learn EL is to spend time reading the online tutorials and then get into reading the user guide paying particular attention to the reserved words and functions. Then go into the strategies and indicators that are provided with the paltform and pick the code apart making certain that you know what each of the coding section actually accomplishes. Then if you get stuck on something you can ask me 🙂
It has been a while since I programmed in the TS2Ki, but I still own a copy and can try to help with coding issues. I am a TradeStation EL Specialist and also a TS Registered Developer.
