Hi,
If I am trading the 4H time fram, do I set my trade according to it or can I go to the 1H time frame and see if my entry signals are met on it so Ican execute my trade?

Thank in advance

Hi, if you can make a backtest on two time frames, there is no problem to trade by this strategy. Regards Greg

Use higher time frame to gat accurate information about the price. If you are using h4 to trade setup than use h12 for get more information.

So, analyse on the longer time frame and enter on the lower time frame?
