Advice on what to learn and practice for CFD trading

I have 3 live trading accounts. One of them is 1200 and the rest are 200 each. The 1200 USD account is meant for long term Trades for long term gain whilst one of the 200 accounts is meant for small profit withdrawals keeping that account at 200 and the other is similar but with longer sustain.

Am I right what's the way forward with this formation? Anything I should consider?

I have been trading for a while year now I have an OK strategy but one which only works with trends. I want to learn more and practice just don't know where to start.
