MODE_TICKVALUE and MODE_TICKSIZE

[[Deleted]]

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.

     * 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). */
