This is exactly what I did, so far I've had unexplained crashes in the algo and all the algo does is collect OHLC data and exports it into excel. I think it maybe due to the Analytics blocks as I've noticed it can be unstable or buggy, so yesterday I built my own OHLC bar system in ADL and testing that to compare. So far the outputs are matching the analytics block outputs and I guess I will see how stable it is. This algo has to run literally all week as soon as market opens to as soon as it closes, so it can't crash.
I will report back with my findings. Ideally I would just like an excel plugin rather than running a whole new charting system alongside my system but I will see. Thanks to the ppl that have replied
