Newbie's question: The built in ZigZag indicator allows only one data series so it can't connect the valley and peak. I'm trying to revise the script to allow for two data series input (both high and low of each bar). What do I need to do after modifying and saving indicators.c so that the new script can be compiled and used in my testing?
indicators.c can not be modified, it is just for seeing the source code. But you can copy the code out of indicators.c into your script and modify it there. Some tiny syntax adaptions must be made due to different compilers, f.i. Max() in indicators.c is max() in lite-C.
