Two ideas:
1. Buy if the market retests at the red trendline. I would not enter without that confirmation. Other confirmations for this trade are engulfing candle and that zone respecting the fib taken from previous low to high.
2. Sell if the market breaks the red trendline. I would look for a candle confirmation and also I would wait for the market to retest at a significant level of support that was marked in a higher timeframe (4 hour). This level was marked in green.
