Nifty 50 Flag pattern?

NSE:NIFTY   Nifty 50 Index
1. if Nifty opens flat to negative, good for short in the range of flag
2. 15175 shorting position, 15000 -15060 could be the target range
3. RSI 15mins, 30mins, and 1hr @60 taking resistance, daily @70 - a combination that could repeat one in a while I believe
4. BNF looking week that could possibly help the shorting easy.
5. price structure in F/ Flag pattern a trending structure
