Price have touched a key level which is pretty robust. Enter market if price action confirms a bullish move upwards. Otherwise price might fall again to the Strong Support level and we might get our chance to go long there instead. I would recommend to set Stop Loss under Strong Support Line if someone wants to take the Trade on the key level. It is more secure and if price suddenly falls to the Strong Support Line we still have a chance to come back with a bullish move. But I recommend to wait for Price Action.
