Frequently asked questions

How do I place a paper trade?

Use the POST /v1/orders endpoint with your API key. Specify the symbol (e.g. 2222 for Aramco), side (BUY/SELL), order_type (MARKET/LIMIT), and quantity.

What are Saudi Exchange trading hours?

The Saudi Exchange (Tadawul) trades Sunday–Thursday, 10:00–15:00 AST. Orders submitted outside these hours are queued as PENDING and fill at market open.

How is paper wallet commission calculated?

Commission is 0.155% of trade value, plus 15% VAT on the commission — matching standard Saudi brokerage rates. Fees are deducted from your paper cash balance automatically.

How does slippage work on market orders?

Market orders include realistic slippage based on order size vs. average daily volume: 0% under 1% of ADV, 0.1% between 1–5%, and 0.25% above 5%. Limit orders have no slippage and fill at the exact limit price.
