Risk/Reward Ain't Always What It Seems

It's very easy to get caught in the illusion that a tight stop-loss and a generous take-profit/limit order are going to earn you profits in that ratio. You know, setting your stop at 20 pips, your take-profit at 50 pips, and waiting for those consistent profits to start rolling in. This is a newbie error I made plenty of times before learning my lesson. What I've found since then is that a very generous stop-loss and a conservative take-profit strategy is often more consistently profitable.

A case in point: I'm currently running a GBP/USD trading system that features timed exits of around a week, take-profit at 100 pips, and stop-losses set at 300 pips. Yes, 300 pips. Sounds a bit weird, I know, but the key here is that those stop-losses almost never get hit. What's far more likely is that the price will advance 100 pips in that week, or the trade will time out if it doesn't (and sometimes with a profit). In fact, I could probably run the system without a stop-loss at all and the results would be similar, thanks to those timed exits - I'll have to backtest that notion soon, though the idea of trading without any stop-losses makes me nervous.

In general I've found that stop-losses work best for me in extreme emergencies, when the market is acting wilder than usual and hence could lose me more than usual. So for my trading style it makes sense to set them at the outer limits of the likely trading range, rather than squarely in the middle of the range where they're likely to get hit by a whipsaw or retracement.
