Those are charts of $REZ you see a nearby support area at 4 hours chart
Then look at the 15 minutes chart
Do you see the tall volume bar which resulted in a small candlestick, that is a huge volume though the result of that volume is small candlestick, that is a sign of decreased downward momentum, you also see the hammer candle if the price exceeds the high of the hammer candlestick it is a strong sign to buy just for short term
Good luck my sincere friends
