Everyone on one chart
Percent since the start, by today, this week or all time. A reset gets marked right where it happened.
The scoreboard for a month-long paper-trading contest between friends. Link a practice account once, then watch the standings move while nobody's trades are ever shown.
Balances tick up in green and down in coral. Rows slide to their new places with arrows, and the leader card lights up the moment the lead changes hands.
The real app running on sample players. Bull Pit reads every account once a minute and the board refreshes itself; this clip is sped up.
Every screen below is the real app, filled with sample players.

Percent since the start, by today, this week or all time. A reset gets marked right where it happened.

Best day, worst day, biggest drop and days in first, built from daily closes so it's the same for everyone.

Every account is checked every minute. A reset, a wrong start or money moved in freezes the player at the bottom.

Trading days left, market closures, half days and the big public events that move everything.

Friends join from a one-time invite. Bull Pit can read a practice account, never trade, and keys are stored encrypted.

Opt-in alerts carry names and ranks only, never amounts or trades, and they go quiet overnight.
One tap swaps the range, from the opening bell to the whole month. Scroll down and every player has a card with their own story.

Bull Pit is a private scoreboard for practice accounts. It is not a brokerage, places no trades and gives no investment advice. Players and balances shown are sample data.
Private leaderboards, invites and alerts, made for your group and nobody else.
