If a large seller (e.g., 1 million shares) is present on Level 2 at a resistance level, the stock is unlikely to break out past that level.
"if there are large sell orders on the level two right then those large orders on the level two are telling us the stock is not going to go up to this level that chart is never going to form because there's a big seller blocking the way right... it's now completely unrealistic to expect that this level's going to break right it's just too big of a seller so it's not going to happen"
