The candles have been increasing and decreasing, and now the candle is currently in the middle between support and resistance lines. There are two possible options here. If the candle goes up, I can wait for an open-close candle above the resistance line then buy it. If the candle continues to decrease, I can wait for an open-close candle below and then sell it.

To add to this, it is risky, but I can buy at the support, sell at the resistance inside the flag pattern.
