On a standard volume bar, 500 shares traded looks the same whether it was one institutional order or 500 separate 1-share retail orders. The bar only tells you the total — it doesn’t tell you how that total was assembled.
Smart Tape removes that ambiguity. It shows every execution as a separate print, in the exact order it happened, without merging small trades together or splitting a large one apart. Each line on the tape is one real trade — nothing more, nothing less.
You see the exact size of each execution, the price it hit, and which side of the spread paid to get filled. That last part matters: it tells you whether the buyer was aggressive enough to lift the offer, or the seller pushed through the bid — the kind of detail a volume bar alone can’t show.
Put together, that’s the difference between a real block trade and a hundred retail clicks that would otherwise look identical on a chart.
