Blast-Off Momentum For ThinkOrSwim

[mbarcala]

This study is an alternative experimental interpretation of the Blast Off Indicator by Larry Williams.
This formula takes positive and negative magnitudes rather than the absolute value. The result is then smoothed with an EMA, and twice smoothed to provide a signal line.

I would like to have this converted

I would like to change another piece of pine script to TOS. I convert few lines but I have others part that I can't understand, never done pine script in the pass.

i compared the TV indicator and TOS indicator....the result aren't the same. Can you please check again @samer800 Thank you!

I didn't find any issue with the script.
However, any scripts depends on the input data received from the exchange. (like open, close..etc). The data received may slightly vary between the platforms/exchange.
