Difference in price not exact

[bluesoul40]

If you calculate the difference between 2 prices (let's say High[3] - High[0]) and print them you'll never get a round result for a CL contract. If there is a 5 ticks difference it will show 0.050000000000006 or 0.0499999999999963
In my case it makes a big difference in a strategy profitability if I round or not these values.
It's consistently much more profitable when the difference is below 0.05 than above 0.05. Do you have any ideas what determines that the difference will be slightly above or below the theoretical value as it seems to obey to a kind of logic ? (at least in my strategy)

I think it has to do with rounding to the nearest float number. I need to study this https://ninjatrader.com/support/help...arithmetic.htm

Hello bluesoul40,

In C# math between doubles can result in long numbers for decimals. You can use Math.Round to round a number to a specific place. If you want the tick size you can use RoundToTickSize

Thank you. In fact my strategy is working with 2 different logics. The one involving this rounding is the less profitable and because of the rounding issue it was showing less trades, showing better results
