I will take as many trades as I can as long as I am never over a 4% risk total, so if I was to see a trade and I was max out I wouldn't take another trade unless I could move one trade to break even early. I would look for the best pair with regards to price strength to weakness, by this I would check both cross pairs strength to weakness. Lets say we have a euraud and eurgbp both showing a sell signal, but when we look at the aud cross pairs all are weak apart from the audchf, where the gbp cross pairs all gbp are strong then you would take the eurgbp sell. hopefully that makes sense.
