Crossy Tape
Hop across a real trading session: every car is a trade
Every lane is a minute. Every car is a trade.
You’re crossing one ticker’s real trading session, minute by minute, from the opening bell to the close. Each busy minute is a two-lane road: its buys drive right in the near lane, its sells drive left in the far one. Get as far into the day as you can.
A replay of a real session’s trades, scaled into traffic. The tape doesn’t receive every trade in the US market. Not financial advice.
What’s on the road
A vehicle’s size is its trade’s dollar value (price × shares), on the same scale as the Fish River’s fish. Green vehicles are buys, red ones sells, and gray ones trades with no aggressor, like an auction print.
- Car under $5k
- Van $5k to $50k
- Truck $50k to $250k
- Bus $250k to $1M
- Train $1M and up: a block trade. The lamps flash before it comes.
How it works
Each minute of the session is a road to cross. A busy minute is two lanes. A quiet minute (the quietest quarter of that ticker’s day) is grass, where you can rest. A minute with a block trade of $1M or more is a railway.
In each lane its minute plays on repeat, ten times faster: a trade drives past at the second it happened, every six seconds.
The traffic is scaled. A busier minute gets more vehicles, up to eight: its biggest trades first, then a sample of the rest. Busy is measured against the ticker’s own day, so on any ticker the open and the close are the hard parts, and every lane keeps a gap you can get through.
Everyone playing a ticker’s session gets the same course, so scores compare. Your score is the furthest minute you reach.
It’s a replay of the session two trading days back. The tape doesn’t receive every trade in the US market, so the traffic isn’t the market’s full volume.
