This error is about how fast you're sending orders, not the total number you've placed. It's a rate limit.
What the limit is
A non-algo API key must send orders at a rate of fewer than 10 orders per second. If your program sends orders faster than that — even in a short burst — the extra requests are throttled or rejected, and you see the "maximum allowed order request exceeded" message.
So you can place plenty of orders over the day; the limit is on orders per second, not the daily count.
What you can do
- Slow down your order rate to stay under 10 orders per second.
- If your strategy genuinely needs to send 10 or more orders per second, you must get an Algo ID approved for that API key. See FAQs for Algo ID in API Trading.
