some rules of trading..
1) wait for test of key s/r levels, implies price will inflect from this levels.
in this situation a test of 904 during trading will give you a setup.
2) trade with volatility or emotion at the highest.. means prices will consolidate less and trend more. Consolidation means higher chance more stop losses get hit.
news reports, or extreme pessimism or optimism...
3) never add to loosing positions
4) have levels where you will admit you are wrong.. stop loss.
protect your money more then risking it..
