First, a definition: When assessing a volume surge, look at it alongside the candlestick. The closing price and the length of the wicks are usually more informative than the trading volume alone.
A common interpretation: If volume surges at a low price and the price stops making new lows, some people see it as a sign of buying support—but this still needs confirmation from subsequent candlesticks.
Calculating your position size based on where you place your stop-loss is much more reliable than placing trades on a whim.
