Yes you can. There are two ways you can do it:
If you simply want to close or modify a position opened by a trading strategy
Go to https://collective2.com/open-positions. You can also find this screen from the Left menu bar->Autotrade->Manage Positions.
On this screen you can manually increase or decrease your positions and add stop orders. All your strategy orders/positions are displayed per strategy which is very useful as your broker software cannot display which strategy a position belongs to.
However, you cannot trade positions or orders not opened by a C2 strategy.
If you want C2 to ignore your non-C2 orders/positions
Enable the "Manual Trading" feature from the Autotrade Control Panel. You can also find this screen from the Left menu bar->Autotrade->Control Panel.
Please note this feature affects your entire account--it cannot be set on a per-strategy basis.
The result is C2 will happily ignore all non-C2 orders and positions, and will trade as if they don't exist.
This means that:
- Let's say you are Autotrading a strategy that is long MSFT and you enter a ES order from broker's software platform, C2 will ignore the ES you traded and go on trading as if it does not exist.
- Let's say you have 100 MSFT in your account and you are setting up Autotrading for a strategy that also has 100 MSFT. If you enable this feature, C2 will ignore your MSFT position and open the strategy's MSFT position, so you will have 200 MSFT.
- Let's say you are already Autotrading a strategy that is long 100 MSFT, and your account is in sync with the strategy, C2 will do nothing because your existing position was a C2 position. If you subsequently trade MSFT manually from your broker's software platform, C2 will ignore the quantity you traded and go on trading as if it does not exist.
