If you are new then maybe try using higher time frames. H1 or something. Even I have tried using autochartist as my brokers fxview and pepperstone provide it free of cost but I didn’t find it to be very accurate. I mostly trade using s/r on price and volume.
I really like to trade exotic pairs like USDRUB because it provides opportunity to play on risk-on/risk-off capital flows, Russian currency is quite sensitive to this factor.
If you are still a beginner, then you need to take those pairs that are considered the most popular and effective.
The choice of currency pairs is quite large, but it is best to focus on what the market offers and what is more relevant.
