Rounding Stop Loss and Take Profit levels...
30 Jan 2018, 16:52

Hi all, 

I'm very confused by the resutls returned below, can anyone see what's happening?!?

This code:

            var abcSL = (UpPatternfib382 - minLow) * Symbol.PipSize;
            var abcTP = (ABCDentryPrice - minLow) * Symbol.PipSize;

returns this result: 

abcSL = 4.57319999999983E-08 

abcTP = 9.41279999999934E-08

and this code:

var abcSL = Math.Round((UpPatternfib382 - minLow) * Symbol.PipSize, 2);
var abcTP = Math.Round((ABCDentryPrice - minLow) * Symbol.PipSize, 2);

returns this result:

abcSL = 0 

abcTP = 0

It seems that the fractional digits don't have any effect on the value returned, always showing 0... Why would this be?!?

Many thanks in advance,

Drummond

Hi Drummond,

This is because you round to the 2nd decimal place. Your values begin at the 8th decimal place. Try the following

var abcSL = Math.Round((UpPatternfib382 - minLow) * Symbol.PipSize, 8);
var abcTP = Math.Round((ABCDentryPrice - minLow) * Symbol.PipSize, 8);

Best Regards,

Panagiotis

Thank you fo rthe quick reponse Panagiotis...

Changing the value to 8 returns this result:

abcSL = 5E-08 

abcTP = 9E-08

Still no good as a calculation of pips to use for StopLoss / TakeProfit levels...

Hi Drummond,

Well that is the value. Would you like to explain to us what you are trying to do? If you are trying to get the pip size of a difference between two prices then you should divide instead of multiplying. See below

var abcSL = (UpPatternfib382 - minLow) / Symbol.PipSize;
var abcTP = (ABCDentryPrice - minLow) / Symbol.PipSize;

Best Regards,

Panagiotis
