Skip exporting Signals.csv for DeepLearning -> save time #479591 04/09/20 05:39 04/09/20 05:39

It takes ages, to export the signals.csv datafiles, because I'm using indicators which rely on R and the slow R-Bridge. I don't want to let this CSV file be recreated when it's already there. I have incorporated the number of the WFOCycle, Asset and number of columns into the filenames to make these files unique. I know how to check if a file is present, but how can I skip this very step of exporting the signals and creating the CSV files? Last edited by sdh309795gaas; 04/09/20 09:49.

The filename of the CSV file is set with this: Code string signals_csv() { return slash(strf("%sData\\%d_%s_%s_%i.csv", ZorroFolder, WFOCycle, Script, strx(Asset,"/",""), Core)); } I thought I'd just put this at the beginning of my trading script: Code if(file_length(signals_csv()) > 0) { adviseLong(NEURAL, 0, 0); //don't want to lose all the convenience!!! return; } I want adviseLong to trigger the neural.train() in R for me. In neural(NEURAL_TRAIN, ...) I'm preventing the CSV from being overwritten with: Code if(file_length(name == 0)) file_write(name,Data,0); However, the training in R isn't triggered. Why?
