Specification

I need to write a library to calculate Required Margin in MT4 and MT5 according to the following requirements:

Create a ReqMargin class and add a public function in it

double ReqMarginCalc(string symbol, double lot)

which calculates and returns the required margin for the given symbol and lot.
The function must work for both MT4 and MT5.
It is best to have one common mqh file with the class and divide the code inside with directives:

#ifdef __MQL5__
// MQL5 code
#else
// MQL4 code
#endif

The function must correctly calculate Required Margin for all types of instruments available in metatrader, not only currency pairs but indices, commodities, cryptos, etc.

All source code must be provided.
