A specific scenario at a major level (previous lower high) is described where selling pressure indicated by an engulfing candle and a close below suggests a short trading opportunity, which was observed to lead to downside movement.
"once we get up there we look and see if we can get a trading opportunity here we have a big swing high it turns into an engulfing candle it's big and red we have a close below right beside it we're seeing selling pressure since we're seeing selling pressure at a major level that might be a time to enter the trade and as you can see this market took off to the downside from that"
