Hi Gautam,
It appears from your chart that your welders Mas are not correct. The first MA should be Wilder's(C,5), the second should be Wilder's(C,8) and the third should be Wilder's(C,13). The reference EMA is EMA(C,50). In your chart you appear to have used double Wilder's like Wilder's(Wilder's(C,5). Correct the averages and see the chart again.
As I am away in another city I am not able to post the correct chat. I am sending this post through my mobile. TS may be able to advise you with the correct chat.
