Buy or Sell - HK50?

Yesterday the market close with a bearish candle. If you focus on the top wick, it tapped exactly 16700 which is a crucial resistance level that HK50 just couldn't break above the past couple days. Thus, I am following thru my theory of a bearish trend until the market begins to find a solid support.

For trading ideas, depends on how the first 15 mins candle open, I will be looking for a sell to minimum of 16274. Depends on the volume, the overall target can be between 16127 to 16000.

For Buy, I will only look for a buy if it is starting to close firm above 16700.
