suggested stop loss, page-18

trader,
typical ruleo of thumb for traders is not to lose more than 2% in a single trade. You would need to look at volatility of share price ie how much it moves recently between the lowest and highest part of the day to help determine stop loss (as there is no point getting stopped immediately through normal daily fluctuation and then calculate your postion size based on cents it needs to fall to get to 2% loss to work out how much you should be investing.

All too late for you now as you are way down and asking advice on stops! Either you sell take the loss or hope for the best that the loss doesnt increase and you come back into profit or lessen your loss. Can't advise yo either way. Next time work out your exit plan before purchase.
