Tick Value problem with Calculation of Profit

[victor21]

Hello,

I have a problem which is quite simple but drives me crazy :

i'm trying to calculate Profits shown in my Backtest (USD) with the amounts of pips and the lot , here's the formula

pips * lots * (MarketInfo(pair, MODE_TICKVALUE)/ MarketInfo(pair, MODE_TICKSIZE))

the values are : 0.0030 points

0.5 lots

77697.059 as ratio

result = 116.54

And the backtest return 108.35 !!

So i searched and i found this : Open price is 1.38134 Close price 1.38434, considering the close price the tickvalue for a lot is (1/1.38434)*100 000 = 72 236.58

with the above formula : 0.003* 0.5 * 72 236.58 = 108.354 !

my conclusion now would be that Tick value which returns 0.777 is wrong and the real one is 0.722

Am i correct ? and if so how can i fix this, i need to calculate upcoming profit only with pips ...

Thanks

in backtest the tickvalue used is fixed , the current one is used, like the spread, thats why the calculation fails ...
