ISA Break Up Big Orders?

To T212,

This is for the ISA account, using buy stop orders - although please address limit & market orders if different.

Do you recommend splitting up larger orders into smaller ones? To ensure we get filled at least partially?

Correct me if I’m wrong, but if I submit a buy stop order for 1,000 shares of any equity - currently if I submit it as one order, I either buy 1,000 shares (order gets filled entirely), or my order doesn’t go through (doesn’t get filled at all). Is that correct?

I’ve never had a case where I’ve only been filled partially, so this is why I’m asking.

Thank you,
I appreciate it!

Not necessarily. If you place an order for 1,000 shares, it may be partially executed if only a portion of the shares or value is available at the time. The remaining shares will stay pending until the order can be fully completed.

Okay, good to hear.
No need to break up my trades then.

Thank you!
