Price looks like it could possibly form a head and shoulders pattern before selling back to this 4H trend line. Wait to first see price break below this gray support and resistance zone with the blue line passing through it before looking for a sell entry on a lower time frame. If this happens we can lookout for the break and retest before taking a bearish trade.
However, there is also the possibility that price could decide to respect this zone and continue to use it as resistance for future buys. Wait for additional confirmations before taking either trade.
