Ok for the multiple timeframe analysis 
and if something like this happen what should I do? (using this method)
higher time frame say "hold" and primary trend say "sell", I think it's sell.
edit:
I mean what information the longer time frame give? The trend of the market? That's what I suppose.

Yeah, in that situation, you'd exit your position if you were relying on multiple timeframes.
The longer timeframe tells you which direction you should be trading. The shorter timeframe tells you when you should be trading.
My personal opinion is that multiple timeframes tends to confuse things, so I prefer to stick with analyzing a single timeframe. If you're able to use it to your advantage, then by all means, test and trade!
Alright
thank you for all this advises I'll test it and validate. It confuses a bit but if you're just looking at the direction of the highest one it's not that confusing 
Thank you anyway for all this good tips you give and all this explications!
