Why division don't works??

[savio12]

it's impossible to calculate this:

why??????

[Linuxser]

Because a number divided by itself is equal to zero.

dResult = (dLow/(dHigh+0.0000001));

Is that what you want?

[skero6]

it's no the same number because dlow is the previous imomentum value and dhigh is the present(today) value of imomentum. previous\present is my purpose but it 's impossible to calculate.

You should ensure the momentum lookback period has been accounted for, as well as the check-for-zero...........
