Rookie investor here...what does it mean if an order has been filled when buying an ETF/Stock via limit order, while doing it manually. Does it mean that the ETF/Stock has been purchased?

Yes Sir! We when bid for a position we need to wait for it to be filled. Once it’s filled the shares are yours/ your position is filled.

Hi! You're absolutely right. When an order has been filled, it means the order you have put in (whatever the limit price is and quantity), is fully purchased/sold.

Because sometimes if the volume is not enough, your order will be partially filled at different prices. That's why there is a differentiation. But by and large, if your broker states that your order is filled, means the order has successfully gotten through, either buying or selling.

'Your buy/sell order of 'qty' 'ticker symbol' has been filled'

something like that.

Hope that helps!
