​
Available Position Data

Net Position: Current position quantity, long or short, per instrument Cost Basis: Average entry price, total cost, unrealized P&L calculation Realized P&L: Profit/loss from closed positions, per instrument and aggregate, intraday and cumulative Position State: Open positions, position changes from trades, real-time updates

​
Intraday Updates

Are positions updated intraday? Yes. Positions reflect real-time execution state, clearing state, and risk calculations. Positions update as orders fill, trades clear, and risk limits change.

​
Position Streaming

Are position updates streamed? Yes, via the Positions Subscription API. Subscribe to receive real-time position updates: 
POST /v1/positions/subscribe
{
  "accountId": "your-account-id"
}
Updates are pushed whenever a trade executes, a position changes, or risk metrics update.

​
Querying Positions

REST endpoint: 
GET /v1/positions?accountId=your-account-id
Returns current positions for the specified account: all open positions, position quantities, unrealized P&L, and cost basis.

​
Risk Management

Risk Limits Trading accounts have risk limits: maximum position size per instrument, maximum notional exposure, buying power limits, and concentration limits. Exceeding limits: Orders that would exceed limits are rejected; position-reduce orders are still allowed; limits are enforced pre-trade. Monitoring risk: Query current positions and risk metrics, subscribe to position updates for real-time monitoring, check account details for buying power.

​
Buying Power

What determines buying power? Available cash balance, collateral value, margin requirements, and risk model calculations. Checking buying power: 
GET /v1/accounts/accounts?accountId=your-account-id
Returns account details including current buying power.

​
Position Reconciliation

Best practices: Subscribe to position updates for real-time state, periodically query positions endpoint to reconcile, use tradeId and execId for audit trail, compare position changes with execution records.

​
Mark-to-Market

Positions are marked-to-market using current market prices (for liquid instruments), settlement prices (for less liquid instruments), and daily official settlement. Unrealized P&L is calculated from current mark vs. cost basis.

​
Position Lifecycle

  1. Order fills → Position opens or changes
  2. Trade clears → Position confirmed
  3. Mark-to-market → Unrealized P&L updates
  4. Position closes → Realized P&L recorded
  5. Settlement → Final P&L determined

​
Multiple Accounts

If you manage multiple trading accounts: each account has independent positions, risk limits apply per account, query positions per account using accountId.

​
Position Reports

Download position reports for end-of-day positions, historical position snapshots, P&L statements, and compliance reporting. See Reporting for report access.

​
Troubleshooting

Position doesn’t match expectations Check:
  • Have all trades cleared?
  • Are you looking at the correct account?
  • Is there a pending order that will affect the position?
  • Have you received all position updates?
Unrealized P&L calculation differs Verify:
  • What mark price is being used?
  • What cost basis is being used?
  • Are fees included in P&L?
Can’t place order due to risk limits Check current position size, order size would exceed limits, available buying power, and account status (active, suspended, etc.).
