you could provide some code to see what issue you have, its better than just guesswork what your issues may be.
The trade just happened, but no plot.
I think it is too little data in C98, if I change to another data not so little (with BTC data 90% of the length), then the graph will show normal. There should be some problem with the logic of plot.
You can try to reproduce this whit data feeds of different start time. But need to override the prenext method to make trade happen when there is only one data feeds have valid data
You then need to have 5 optimizations (the sample shows 2) and the StFetcher instantiating the appropriate strategy with the appropriate parameters. In the example idx is used as the key to decide which strategy to return. The same idx can be used to decide which strategy to instantiate and with which parameters.
