Yes, but you have to code it yourself out of one minute bars - and this takes a bit more than just a few code lines :(
But search so much has already been coded may be this as well.
Short answer: No!
Long Answer: You can create Custom Symbols with user-defined time-frames but that will not change the allowable standard time-frames used in many functions. So the answer is still, no!
if I can use custom periods in the standard indicators it is valid for me.
As I stated, you cannot use custom periods in the standard indicator functions. You would have create your functions or indicators to build up the "custom" periods off of 1 Minute Bars, much like the Custom Symbols would also use that technique.
In other words, you would have to code all your own functionality around the concept of custom time-frames.
It sounds extremely laborious and difficult ... :(
It depends on your level of coding skill and knowledge.
Until now, my programming skills and knowledge have always been one step behind my concerns. I think that's why I improve day by day.
At some point I will try, because I'm sure it would improve the strategy I'm optimizing.
It is a good challenge for me.
It's always a good challenge.
Just keep trying until you succeed.
