NAS100 Short

This index has formed a bearish pennant formation and has bounced from the major resistance zone. According to the market sentiment, most traders are long( around 72%), which might be a major indicator that the price is likely to go reverse of that. My prediction is that the price will move downwards, so as to complete the pattern formation ( according to 4H) timeframe.
I have two entry scenarios, first the London market may push the price to 12080 / the resistance zone, or at 11960 where the market may break the support zone and move further downwards.
Risk : Reward ratio at 1:3, with a risk of 1-2 % of the trade. Target is at 11700.
