Banknifty ahead of Election results and expiry as well has been forming a triangular formation in 15 Mins timeframe . Breakout from either side and a close on 15mins candle can be better for a buy or sell. Better to avoid trading within the triangle. But since it is a big event and expiry we can use this analysis for watch & learn than to place a risky trade as it can tend to be volatile.
