Some issues:
2) RSI (of which I'm not a fan -- have never seen it work well) has much sequential content, and therefore its direction is as much or more important than its level. So, using 'level' only is using half of the RSI's available story.
3) On-Balance Volume -- how does one use that in a forex case, which lacks volume??
4) assuming you're going short, then the stop-loss should be set at level of upper Boll.Band.
[EDIT:] Otherwise, you've got:
middle BB: Entry
lower BB: stop-loss
below lower BB: take-profit
Are you saying that volume indicators are worthless in Forex? Why don't they have volume?
