Would someone please let me know how to create a histogram plot that is different in colour depending on the axis side

Example, the indicator gives a positive value resulting in histogram plotted bar above zero axis and coloured green, but when indicator gives a negative value, the histogram plotted bar is below the axis and a different colour, say red.

I think this distinction would be very useful if it is possible
thanks

Try creating 2 signals (2 TI icons) with the same calculation (it may not work if you use advanced options live avg)
Use MathMax in one TI and MathMin in the second TI. Lets say your calculation is A+B.
Re write it as MathMax(A+B,0) and MathMin(A+B,0). MathMax and MathMin act as filters to show values >0 and <0 respectively.

Here MT4 documentation about it:

double MathMax( double value1, double value2)
Returns the maximum value of two numeric values.
Parameters:
value1 - The first numeric value.
value2 - The second numeric value.

Sample:
double result=MathMax(1.08,Bid);


double MathMin( double value1, double value2)
Returns the minimum value of two numeric values.
Parameters:
value1 - The first numeric value.
value2 - The second numeric value.

Sample:
double result=MathMin(1.08,Ask);

If you need the signals to be used with the strategy builder you don't need to use 2 TI and MathMax/MathMin, just comparing the indicator to zero (>0 or <0). You need 2 TI if you want to see the 2 signals.
There may be a work around, create on

thank you!! , I will try this....and post outcome
