There was an easy day trade setup on crude oil for the 14th today where market tested its daily bullish reversal(62.1) you could of shorted the market at that point knowing that the array had a directional change the very next day. As long as the market stayed below that resistance level the risk was to the downside. Reversals are simply key areas of support and resistance and should be traded as such.

IF you trade elected reversals only you need to know that the expected move should occur within 1 to 3 time units so we had previously in the EUR/USD 3 weekly bearish reversals that were elected by just a few ticks the market then rallied for the next 2 weeks testing its weekly bullish and then on the 3rd week started moving lower towards the next weekly bearish, the array can often warn of such an event. So let those elected weekly bearish reversals provide resistance and if the market moves above them the risk is then to the upside.
