SET short opportunity

The SET index went up above 1750 to ~1760 but then closed below 1750 on the same day. This 1750 is significant as it is the current 61.8% fibonacci retracement on the downtrend pattern.

Daily chart now showing a doji price action and assuming the current rebound from 1600 is a B wave, I am expecting a sell-off for today (the 20th Sep).
