Using SAR as an alrenative...

This has been pretty poorly coded. The chandelier stops s adjust downward in an uptrend and upward in a downtrend.  

Lines 105 and 106 should be:

             var r3 = pivot + 2 * (high - low);
            var s3 = pivot - 2 * (high - low);

Hi,

S1, S2 and R1 and R2 are correct for 60 minute based on classical calcualtion

S3 and R3 are wrong.

Please note: 

R3 = R2 + RANGE

S3 = S2 - RANGE
