Hmmmmm not sure I agree Pete.
If you trade random entry and
Target 10 ticks, stop 10 ticks - you breakeven MINUS the spread
Target 100 ticks, stop 10 ticks - you breakeven MINUS the spread
Target 48848920 ticks, stop 100 ticks - you breakeven MINUS the spread
Target 1ticks, stop 100000 ticks - you breakeven MINUS the spread
Doesn't matter how you change it - you will still breakeven on the trades but lose the spread on top.
If you change to a trailing stop, then what happens is you will make money if the market mostly trends. Although not quite that simple (you need to be aligned with the overall volatility), the trailing stop makes it a trend following system.
I think The Hare has already fessed up on what his to$$ing involves to an extent. I think when he says random entry, a lot of people presume he has an equally unsophisticated exit strategy. I would doubt that because he's already been in discussions here about the feeling of being 'engaged' to the market and how you somehow feel more able to read the action once in a trade.
Still - he's not willing to feed the monkeys right now, although he may have to do that as penance when the RSPCA turn up at his house about those bagged cats.
If someone's PROFIT target is 10 ticks, then that includes the spread.
If their LOSS is 10 ticks then it includes the spread.
What's all this plus and minus the spread - if the spread wasn't included it wouldn't be 10 ticks profit, would it.
