While we generally discourage day trading, it is technically possible to do on Wealthsimple Trade. As soon as a purchase order is filled the asset becomes eligible to be sold, and as soon as an asset is sold you can immediately use the proceeds to trade again.
Keep in mind that trading the same security within the same day should be done with caution and that participating in this strategy means you are accepting any risk associated with it.
In addition, day trading can be flagged as inappropriate trading activity. As such, Wealthsimple reserves the right to block transactions at our discretion if we notice suspicious activity.
