If you first need to translate your system into PRT, then the initial preloaded history of 10000 units in your lowest timeframe (1s) will only give you between 2 and 3h history when user launches the system (and I would suppose you don’t plan to expect users to wait live after launch for as many days as required by your longest period used in the daily timeframe part of the code before the system finally enters a usable period, which, in case of order rejection leading to system stop, would require user to relaunch sytem… and to wait again…)
Anyway, that wasn’t your question, you wanted selling guidance, you’ll find it there: https://market.prorealcode.com/become-a-seller/
