MarketInfo function in mql5

New comment
 

what is the equal of this mql4 code in mql5 :

double  PointValuePerLot(string pair="") {

    if (pair == "") pair = Symbol();
    return(  MarketInfo(pair, MODE_TICKVALUE)/ MarketInfo(pair, MODE_TICKSIZE) ); // Not Point.
}
 

This is valid for both MQL5 and MQL4+ ...

Symbol Point Value

double
   dbTickSize   = SymbolInfoDouble( _symbol, SYMBOL_TRADE_TICK_SIZE  ), // Tick size
   dbTickValue  = SymbolInfoDouble( _symbol, SYMBOL_TRADE_TICK_VALUE ), // Tick value
   dbPointSize  = SymbolInfoDouble( _symbol, SYMBOL_POINT ),            // Point size
   dbPointValue = dbTickValue * dbPointSize / dbTickSize;               // Point value
Remember, it's best to use tick size and tick value in your calculations, instead of point size and its value.
