As observed from this 5-min. chart from Russell 2000 (TF), a low risk short trade is probable.
From the previous trading closing area (the previous arrow), and from the opening with a new high of 799.50 points.
By observing this chart pattern and by combining the previous closing chart, you can conclude that this is an HS pattern.
Likewise the descending 20 ema is a short trade confirmation, plus the previous close was broken at the last hour of trading.
By taking a last hour short trade is a sure fire to bank some money (777.00 - 773.00 = 4 points). TF moves 0.10 points per $10.00, that's +$400.00 bucks profit.
Not bad for the last hour trade.
As the great trader say, "waiting and sitting" coupled with Observing is the way to Trade!
