Bankroll tracking and position sizing warnings in Kuroko

Tell Kuroko your total trading bankroll and it will warn you before any single trade consumes too large a share of it — protecting you from oversizing.

Bankroll tracking lets you set your total trading capital so Kuroko can flag when a proposed trade is disproportionately large relative to your overall size. Set it once in the order terminal and you will see automatic sizing warnings on every subsequent trade.

Set your bankroll before placing your first live trade. Sizing warnings only appear once a bankroll is configured, and a single oversized trade early on can skew your overall results.

How to set your bankroll

Your bankroll is configured directly in the order terminal at /execute.

1. Open the order terminal

   Navigate to Execute in the top navigation bar. This is the direct order terminal with the live order book.

2. Enter your bankroll

   Find the bankroll input in the order summary panel. Enter your total trading capital in dollars — this is the full amount you have set aside for Polymarket trading, not the amount in any single position.

3. Confirm a market and size a trade

   Select a market, enter your shares and limit price, and review the order summary. Kuroko calculates what percentage of your bankroll the proposed trade represents and displays a warning if it is over the threshold.

Sizing warnings

When you size a trade in the order terminal, Kuroko compares the estimated cost against your bankroll:

Trade size	Warning level
More than 10% of bankroll	Caution — percentage shown
More than 20% of bankroll	Strong warning — consider sizing down

The warning appears inline in the order summary before you submit, so you can adjust shares or limit price before committing.

What bankroll context shows you

Beyond the per-trade warning, the bankroll service tracks your full trading activity and surfaces the following context:

• Total deployed — the total capital committed across all confirmed paper and live trades
• Realized P&L — the sum of resolved trade outcomes (wins minus losses)
• Win rate — the percentage of resolved trades that were profitable
• Category breakdown — how much capital you have deployed across market categories (Elections, Crypto, Sports, Economics, Tech, World)

This context is visible on the portfolio page alongside your trade history.

Trade size limits

Regardless of bankroll, Kuroko enforces the following hard limits on every trade:

Limit	Value
Maximum shares per trade	10,000
Maximum cost per trade	$10,000

These limits apply to both paper and live trades.

Storage

Your bankroll setting is stored locally in your browser via localStorage. It persists across sessions on the same device and is never sent to any server.

If you clear your browser data or switch devices, you will need to re-enter your bankroll. Your trade history is stored separately and is not affected by clearing the bankroll setting.
