Difference between a close and open.

[ForexTrader17]

How would I code something like this: The Close[2] = Open[1] +/- 3 pips. So basically I do not want to see a difference of more than X pips between  the close and an open of the following bar. Is there a function that does it? Because it can a positive or negative value depending on how you subtract it.

Thanks.

MathAbs()

Something like this? MathAbs (Open[1] - Close[2]) <= 3*myPoint

another way

if(Close[2]>= Open[1]-3*Point && Close[2]<= Open[1]+3*Point) bla....
