Forget and stop circulating TTI, I think is just a sale speak, whether their Metastock are really showing parabolic trends is a question mark. Unless you can provide the metastock code then we can test it out.

Since you shown interested in GMMA. Then learn the parabolic trends knowledge from Guppy.

Hi here is one parabola afl, with errors.

If somebody can fix the errors,then we can take a step forward.
thanks

hi hmsanil

Thank you for the corrected code.

this forms the step1
the second step,
step2 is how to modify the variables to get sharp parabolic curve
which may fit top few fast risers.
step3 is finding a suitable stoploss for the parabolic move of super risers

once again thanks for your fast response!

best regards
ford

oops, I Hardly know anything about coding. I saw this indicator and searched on net and found the correct code. Then i posted here as you asked it

Sorrrrrrrrrrrrrrrrrry.

But there is kevin,Johny and many more who can do this.Lets hope they can help us out.

Thanks
