If during the next 2 weeks, price doesn't drop further, we can long it safely. If we break above 8831.55 before that time runs out, bears will be in trouble too.
Keep an eye on the uptrend slope, indicated by the speed line under the current prices. This line has to hold if we see a retracement. You can use an ATR based stop loss to trade this trend. 3 times the 11 period ATR value is a good start. Right now, we can buy on a break above Friday's high and stop at Friday's low.
There's plenty of time to get further confirmation, don't risk over 1% on any given trade.
Now, longs need a new daily high to enter again safely, and tighten stops to Oct. 13th's low.
