If your in a trade and in the money, to recycle, if price closes above 9ema but right away fails back under it, add to your short position on the fail of the 9 ema with a stop at the top of the recent relative high ( see chart below for example)
PM trading -
volume needs to be 50-60k, if above 100k avoid shorting
look at first GZ rejection on first bar that opens below and stuffs into GZ
if big gap between 9ema on 5min chart and price - look for short
