Hey Andrew,
So, regarding the lot size, that depends on the account size. For example in an account of ours that we have 500$ in, we trade 0.01 lot size. That is our preference as we think this is low risk trading.
To see the distance for the stop loss, it’s good if you use a risk or pips calculator as this should display the distance in pips so that you can set the correct pips for the stop loss on the pair you want to trade!
Hope this helps!
If you have any more questions, let me know!
Kind Regards,
Nikos
