Opening range breakout strategies

Any indicators that we can use to make sure that the range breakout is not a false signal? We can use volume I guess but what should be the criteria for that? Any other suggestions please share.

Sometimes what I do is that I check if the overall market trend is bearish or bullish. If it’s bearish I go for low break out and vice versa.

you can check the size of first candle and the volume of the breakout candle
