Cricket – the way I see it you’ve got 3 options:-
1. Cut now and put it down to experience, and hope that you can get it back quickly on good trades.
2. Open a ‘balancing’ long – this way you won’t be losing (or gaining!) any more, and when you’re SURE that a downtrend has started, close long and open more shorts (bigger ones?) which could bring you to breakeven and onto profit quite quickly.
3. Average up by opening more shorts as the price rises; which could get your money back quickly on retracement, but adding to a losing short position in a bull market is plainly dodgy – the index could rise another two hundred points before it has a serious retracement.
The market has had an incredible rise, and any disappointment in the earnings season, which is just starting, could take the index sharply down several hundred points.
It all depends on how deep your pockets are, and how strong your stomach is!
The first cut is generally the cheapest, and a tight stop-loss is your best friend in these volatile markets imho
but you know that now..... :|
