Position Not Fully Exited

This message indicates that the current open position will not be fully exited, and as a result, a new position cannot be entered on the other side. TradersPost requires that the existing position be completely closed before a new position can be initiated. This is a requirement by the broker as you are not allowed to be both long and short on the same symbol at the same time.

For example, say you are long 100 shares of AAPL and you send an exit signal with a quantity of 50:

{
    "ticker": "AAPL",
    "action": "exit",
    "quantity": 50
}

You will still have 50 shares of AAPL remaining so TradersPost will not try to enter a new position on the other side.
