How to create + plot range bars from incoming OnTick() environment for me to trade from

Hello, first post and please excuse bit of mt4 digression but not know how else to state my issue.

In mt4 I generate .hst files holding xPoint sized bar records. As each tick comes in each record built (via Bid used to update OHLC datums) until bar range at or (potentially beyond specified range). Once met, new .hst record is started,...,...

Now, this .hst file can be loaded/displayed as main chart using this data. So, by running the .hst generator/indicator on a normal mt online chart, each real time tick can be PostMessag'ed() to the offline chart and we see bars build tick-by-tick just like any normal online chart..

Ok, above is what I want to do with cAlgo as various sized range bar trading is where I'm at.

I believe I just need to know that yes... you can do what you have done in mt4 - these are the areas you must learn about.

I understand the need [and profit] to play about and learn 'the hard way' but after 18yrs with metatrader, I'm very uneasy over all this stuff which is used in cAlgo (after all .ru's take on a real C syntax is beyond minimal and mt5's c++ gunk is similarly weak). I used to be s/w engineer but that's decades ago. I want to learn but feel is big ask without getting my butt kicked in the correct direction :)

Well... hope to get response. I am very excited about 'finally' makeing the decision to jump off mt4 ship and get into a real platform (well... this is what hits me to date!!)

Regards

Tim
