Brokers and Trading Accounts

Strategies place orders on a trading account. Accounts belong to a broker connection.

Settings → Trading Parameters (broker connections)

Add a broker connection

  1. Open Settings → Trading Parameters.
  2. Click to add a broker, enter a Broker Name and choose the Broker Type:
    • Virtual — built-in simulated broker for paper trading. No real money, no external credentials.
    • Alpaca — Alpaca account; fill in the Credentials fields.
  3. Save the broker.

Add a trading account

  1. On the broker, add a trading account.
  2. Enter an Account Name and an Initial Balance (USD) (virtual accounts).
  3. Choose a Trading Cost Preset — how fills are charged in simulation:
    • Realistic — typical retail conditions (0.1% spread, 0.1% commission).
    • Low Cost — best-case ECN broker (0.05% spread, 0.05% commission).
    • Zero Cost — no spread, no commission.
    • Aggressive — high costs for stress testing (0.2% spread, 0.2% commission).
  4. Save. The Trading Accounts list shows balance, used and free margin, realized and unrealized P/L.

Start with a virtual account. Every order passes the risk checks (“Risk Management”) before it reaches the account.

Next step: create a strategy (“Creating a Strategy”).
