Converting MQL4 to MQL5 for a Stochastic program and adding a few scenarios

Please convert the below code from mql4 to mql5 language.

on the code, I would also want to close the trade when the profit gets to a preferred value which can be set from pair to pair.

the code should be edited to open multiple trades as recovery and there should be an option to limit the number of trades to a desired limit.

when closing the profit it should not close other trades unrelated to that pair.

the expert should be able to consider other trades of the same pair opened manually in its profit calculation.

Profit calculation should consider swap and commission.

should not have stoploss, Take-profit will be in monetary value not in terms of pips.

on the stochastic, if the main goes above or below the overbought or oversold region and comes again below or above these regions before the signal crosses, the expert should wait for 3 candles, if the signal crosses the thresholds, it can open a trade, on the forth candle it should nullify the scenario and consider it as conditions not met.

the lot size should be calculated based on Account equity.

i need a code that i can run on Metatrader

Code will be supplied to selected developer
