Source code library - Expert Advisors, Indicators and Scripts

Hi niuniu, thanks for your contribution, it comes in handy considering MT5 laks of this indicator.

I was double checking the math routine on your script to make sure it would correspond to how I would calculate pivot points based on different sources (e.g. Wikipedia, BabyPips, etc), and it seems we have a difference on how you calculate the third support (S3).  You have this:

S3 = (2*P)-((2* LastHigh)-LastLow);

I would instead have done it this way: 

S3 = (2*P)-((2* LastHigh)+LastLow);

Notice the positive sign for the LastLow variable.

In fact, if MQL5 does proper order of operations --which I believe it does--, you could safely simplify your routine by getting rid of most of the parenthesis, from this:

         P=(LastHigh+LastLow+close[i])/3;
         R1 = (2*P)-LastLow;
         S1 = (2*P)-LastHigh;
         R2 = P+(LastHigh - LastLow);
         S2 = P-(LastHigh - LastLow);
         R3 = (2*P)+(LastHigh-(2*LastLow));
         S3 = (2*P)-((2* LastHigh)+LastLow);

To this:

         P=(LastHigh+LastLow+close[i])/3;
         R1 = 2*P - LastLow;
         S1 = 2*P - LastHigh;
         R2 = P + LastHigh - LastLow;
         S2 = P - LastHigh - LastLow;
         R3 = 2*P + LastHigh - 2*LastLow;
         S3 = 2*P - 2*LastHigh + LastLow;

Please double check the S3 calculation to check if you got ir right, and thanks again for the script!
