l think as long as your are not a tight scalper there is no much difference between 2 or 3 pips when you will trade.if you are trading long term.and if you will target lets say 50 or more pips spread is not very important.you may focus on your strategy and trading system.spreads will not help you too much.if you dont have a good strategy even 0.1 spread cant help you to make profit.
