MODE_TICKVALUE and MODE_TICKSIZE

New comment
 

Hi,

I dont know the meaning and usage of MODE_TICKVALUE AND MODE_TICKSIZE, the docuemnt said as following:

MODE_TICKVALUE 16 Tick value in the deposit currency.
MODE_TICKSIZE 17 Tick size in points.

and sometimes, MODE_TICKVALUE will be used to calculate the lots size in EA, such as

orderInfo[OL_LOTSIZE][binx]=NormalizeDouble(OL_INITIAL_LOT,LOTDIGITS)+NormalizeDouble(1.0/tickvalue*(money/100*riskPerc/(riskPip)),LOTDIGITS);

would you please kindly explain them in detail?

thanks.

  
double  PointValuePerLot() { // Value in account currency of a Point of Symbol.
    /* In tester I had a sale: open=1.35883 close=1.35736 (0.00147)
     * gain$=97.32/6.62 lots/147 points=$0.10/point or $1.00/pip.
     * IBFX demo/mini       EURUSD TICKVALUE=0.1 MAXLOT=50 LOTSIZE=10,000
     * IBFX demo/standard   EURUSD TICKVALUE=1.0 MAXLOT=50 LOTSIZE=100,000
     *                                  $1.00/point or $10.00/pip.

     * https://forum.mql4.com/33975 CB: MODE_TICKSIZE will usually return the
     * same value as MODE_POINT (or Point for the current symbol), however, an
     * example of where to use MODE_TICKSIZE would be as part of a ratio with
     * MODE_TICKVALUE when performing money management calculations which need
     * to take account of the pair and the account currency. The reason I use
     * this ratio is that although TV and TS may constantly be returned as
     * something like 7.00 and 0.00001 respectively, I've seen this
     * (intermittently) change to 14.00 and 0.00002 respectively (just example
     * tick values to illustrate). */
    return(  MarketInfo(Symbol(), MODE_TICKVALUE)
           / MarketInfo(Symbol(), MODE_TICKSIZE) ); // Not Point.
