Why would anyone want to risk 15 ticks to only gain 5 ticks?
This means that every time you lose, you will need 4 winning trades to break even (plus commissions)
You are making it tough on yourself. Try the opposite :)
Why don't you risk 5 ticks to gain 15? That would be a better approach and risk:reward ratio.
At least if you lose 2 to 3 times in a row you can still break even (or a little less) with a single win.
