Hello

I would like to implement in only one script 4 different strategies using different time frame, I really do not understand how to do this, please can you help me.

Thanks a lot Arns

Did you start reading the manual?

Yeap but I am a newbiee and it is a bit tricky for me

So what you got so far?

A blank page ain't much.

I suggest you to go through the workshops, and buy the black book, then it gets a lot easier.
Don't do the same mistakes I did (and probably still doing).

Really good, I have just bought it... What kind of mistakes did you do?

Main mistake, not buying it from the start.

Is the Black Book a lot different from the manual ? What are the critical differences ?

The black book is a guided tour, so it speeds up entry to the tool with some basic information on building algos, already including some that work.
So it is a good start, instead of starting by manual with C like language, learning the tool itself with its' tricks and traps.
