Nifty- Hammer Doji - will it go to 17757?

Nifty made a hammer doji indicating a bullish reversal. PCR is oversold so is supportive of a reversal. DIIs became net buyers again today, again should act as a support for tomorrows trade. So if Nifty breaches 17310, then it could go to the resistances 17520/17757. What do you think?
