The principle
The tape is the stream of trades scrolling by. Speed of Tape measures its pace: how many executions per second, and at what intensity. A calm market ticks trades off; a market under tension fires them in bursts. Volume says how much; speed says with what urgency.
What DeepCharts does better
DeepCharts measures that cadence continuously and integrates it natively with the rest of the order-flow read — footprint, delta, DOM — rather than treating it as a separate gadget. An abnormal pace spike, dozens of trades in a fraction of a second, jumps out and immediately cross-checks with what liquidity and delta show.
Using it day to day
Day to day, use it as an urgency detector near key levels. Most useful on fast, highly liquid instruments — NQ and ES in the US session, FDAX in the European session — where execution bursts and HFT activity are frequent and meaningful.
Example: the NQ nears a high, the tape fires up violently (a burst of market buys), then price stalls sharply. The last wave of aggressors just got absorbed: a climax. The abrupt slowdown that follows confirms exhaustion.
⚠ The trap to avoid
The trap: taking every speed spike as a reversal. A fast tape accompanies an exhaustion climax as easily as a continuation impulse. It's how price reacts right after the spike — stall or continue — that gives the direction.
Combine it with
Combine it with delta (the effort) and Deep Trades (large activity): speed tells the urgency, delta tells the side, Deep Trades tells who's hitting hard.
FAQ
What is speed of tape?+
The rate at which trades execute (count and intensity per unit of time). It measures market urgency, where volume alone measures only quantity.
How do I spot HFT activity with it?+
Through abnormal cadence spikes — bursts of executions in a fraction of a second, far above the usual pace — typical of high-frequency algorithms.
Does a fast tape signal a reversal?+
Not always: it can mark an exhaustion climax or a continuation impulse. How price reacts right after the spike decides — hence reading it with delta and liquidity.
