The short answer: The Trade Ideas Web Dashboard can replay a full trading day. A Stock Race replay compresses the session into about a minute, so you can see which stocks pulled ahead and when, with heat maps and Top Lists from the same session alongside. It runs in any browser, Mac included.

In one minute

Stock market replay, in one minute

  • Replay a full trading day: the Stock Race in the Web Dashboard can replay a past session from the open, compressed into about a minute.
  • See how the day unfolded: watch which stocks pulled ahead, when, and by how much, with percent and dollar moves on each lane.
  • Check a chart without clicking: hover any heat map tile for a snapshot chart, and use Picture in Picture to see two timeframes at once.

Stock Race Replay

A full trading day, compressed into about a minute

Key point

The race panel has a switch between Real-time and Replay. On Replay it plays back a past session, here October 9, 2026, from the open. The stocks on a Top List (Screener) become lanes, and each lane grows as the stock gains, showing the percent move and the dollar move. In the video, one full pass runs from about 0:40 to 1:52: a trading day in roughly 70 seconds.

At about 1:12, GameStop (GME) pops into the race. Some names move so fast they are hard to click, which is a good reminder of how quickly momentum shifts. A race is built from a Top List, Trade Ideas' stock screener, so you can replay any list you follow. More on Stock Races and the momentum stock scanner.

Heat maps and Top Lists (Screeners)

Heat maps and Top Lists alongside the race

Keep in mind

The race does not sit alone. In the same channel, a scrolling Top List and a heat map show the same group of stocks from the same session. The heat map can sort by change from the close or by change over the last 30 minutes, which shows which names ran into the close.

Top Lists rank stocks on 249 filters, and in a live session they update every 15 seconds. The streaming stock screener page explains how Top Lists and alert windows differ.

Charts

Hover charts and two timeframes

Trader tip

Hover over any heat map tile and a snapshot chart opens, so you can check a stock without clicking away. Open the main chart and Picture in Picture shows a 15-minute chart with a daily chart inset: two timeframes at the same time (2:41 to 2:48 in the video).

Why replay a trading day

Keep in mind

A replay lets you study a session after it ends: which stocks led, when the leaders changed, and how sharp the pullbacks were. In the video, Daniel points to a stock that broke out, pulled back hard, broke out again and pulled back again. Moves like that are why risk management matters, and why a plan to try a setup more than once can help. A replay shows what happened. It does not show what will happen next.
