By default our sim restricts accounts to not trade over 10,000 shares at a time as most brokers charge more fees for trades larger than 5,000 shares as well as 10,000 shares is normally a very high risk trade that can result in very large amount of slippage for an order unless set as a limit order.

The error message normally looks like the one below:

We do not suggest to change this while in the sim to help you understand when you might be trading in a large size, however if you want to change the soft share size limit you can follow this guide here:

If you still get a share size restriction error please email into for us to look into your account further.
