Alpaca executed my order 3 times!

I place an order just before the market opened. It seemed “stuck” once the market opened. Then the Alpaca interface showed the position but the order still existed. I refreshed and all of a sudden it showed 3 orders were executed!?

Did you click when it was frozen? That will send extra clicks and if their UI code doesn’t care to check for the same data being sent in a short time frame, then yea, it will trigger multiple orders.

No. The order was already submitted. It was showing as new in order screen and showing position like it went through. API wasn’t showing positions. I then refreshed my browser it saw the order triple.

Bug in your code maybe?

I was using the Alpaca web interface.

Can you share the order IDs?
