That's great! Can you compare it to MT values, is it similar or way off?

now will look

[babalu4u]

or this

[scheinwerfer]

Doesn't look right. The values at some places are too big, reads more than 10. I had the same sh**.

One other thing which got me thinking - TMA from cT and TMAtrue are not equal, most probably. That's food for thought for now.

[babalu4u]

I will tray with lwma for tmaTrue...

[babalu4u]

OK... now TMA Slope is calculating RIGHT..... YES my first cAlgo indicator and my first C# experience....
Its not to hard to migrate from Empty4 to cTrader/cAlgo..... now I must add a little lipstick to indy and than next project : First EA for cAlgo....

Good job! Your success makes me enthusiastic, I'll try to port it to another platform once more, too.
