You can see why your trade is pending by selecting the trade from the History screen and tapping on “Why Is My Trade Pending.”
Partially Filled Trades:
Trades can be partially filled if there were not enough matching shares available to fill your trade. Shares that were not filled will continue to display in your portfolio. Submit a new trade if you’d like to try to fill the remaining shares.
We were not able to find any matching buy shares for your sell, or any matching sell shares for your buy. Your trade will automatically be re-submitted at your original trade price for the next trading window.
