SYMBOL_TRADE_TICKVALUE_PROFIT / SYMBOL_TRADE_TICKVALUE_LOSS difference?

 
Hello guys,

I am just coding a little tool to calculate the position size. I always used SYMBOL_TRADE_TICKVALUE for my calculations but I noticed today that there are two different tickvalues.
With some pairs both tickvalues are identical and with some pairs they are different. Can someone please explain me this?
