Which is the good time to trade

Which is the righ way to pay or to sell
And which direction is good to trade when the graph is going up or down?

Although, I am a newbie in FX market…
I want to to give my opinion regarding your question…

There is actually a right time to trade and the right pair to trade at the right time …
Considering the Trading session, Like the European session , there is much liquidity that almost all pairs can be traded…

I once asked the same question to my FX teacher,
He told me to be consistent, develop my trading psychology and strategy, ofcourse we know that not all strategy is a 100% win…

The market is volatile; but you can check your trading result on each trading session; Personally I use Asian Trading Session!

Try to follow the market trend; & make your entry-exit points according to the neatest valid support-resistant levels! In my trading, I follow the same!

The best time to trade entirely depends on your session, as well as your trading pair and global economic events, therefore one should be skilled at assessing the movement of the market.

As I see, you are using the 15 minutes trading chart; but my personal recommendation would be higher time frames like Daily or H4 (to identify the market trend)!
