Selecting a percentage option on trading an asset makes CAD approximation $0

[ndizazzo]

Priority

Trivial

Description

When I select any of the 10% / 25% / 50% / 75% / 100% options after the view first loads, the estimated amount in CAD is set to $0.

NOTE: Upon initial entry into the page, the CAD approximation appears correct.

Reproduction Steps

1. Select Trading
2. Select an asset you have a positive amount of (in my case, PTS)
3. Select a percentage option
4. Observe the CAD approximation gets set to zero
