****I'd been told you should always use the higher time frame as your main buy/sell signal and then go down to the lower timeframe, and if both confirm it, you know your signal is more reliable so make the trade.
You should always use CONTEXT for your trading signals. Context mean special conditions, which should take place to validate your signal(s).
Context is essential. Context-less trading signal, if profitable, is so called ‘holy grail’ or signal, which works profitably for any conditions. You can spend the rest of your life in quest for Holy Grail, look here for example:

This thread started 2014 is perfect example of endless loop of searching the universal pattern/signal for all conditions.
There are many ways to define your context, including (but not limited to): time of the day (assume you want trade intraday), key market events and also price action dynamics.
One of the ways to define context is pure price action, but on the timeframe greater than your trading timeframe. I already shared my view how to do it here:
