Custom charts datafeed

 

Is it possible to create custom charts which gets updated like all other charts from a datafeed or is this only possible with using offline charts?

I have currently solutions how to read crypto currency data from exchanges and how to create then offline charts with that data, the charts gets also updated but i dont like this solution so much, i would like it more to create something which updates some data files and the metatarder reads this files and you can open that chart then and switch timeframes, something in this direction i would like.

Would be nice if somebody can just tell me if its possible or not and if possible would be also cool to get some infos where to look.
