Trading correlation pairs by using the other pairs

Only 7 trades today, just waiting for that last candle to close and put the white lines where they should be.
One thing I did not say yesterday: I only put the lines on the bodies of the candle and not the Wicks.
I'm only using a demo account, I'm still ironing things out

I pick 10 of the trades that I was watching today I didn't put them on earlier which I should have done I only basically picked the ones I were going to have but I have 10 that were good trades I didn't like them all just a few of them put it seems to me even though it was a crazy day this system still works
Here are the 5 I had to day

Here are the 5 trades I had today

This was only six days, trading £258 for the six days, the system wins more than it loses. In fact, yesterday I had 15 winning trades,
And I only put on 3 of the trades out of the 15
My problem is that every time I put a trade on, they charge me £5,30
So yesterday I was 15 pounds 90p down,

right at the very start of the trades
And I've not learned how to deal with that yet, otherwise,
I'd be putting a trade on every single one of them because I found more of them win than lose.
