Flatten Positions

The FLATTEN positions command is very powerful. It provides the option to flatten all positions across all accounts, a specific position for a particular instrument in a certain direction in one account, or anything in between.

The FLATTEN command accepts several parameters:

• account

• instrument

• market_position (long, short)

• nothing

The parameters act as filters, searching for positions that match the criteria to be flattened.

Most importantly, if you execute command=FLATTEN; without any other filters, it is similar to the FLATTENEVERYTHING command. All positions will be closed. The only difference is FLATTENEVERYTHING will close all positions and all orders across all accounts.

If FLATTEN is executed with both an account and an instrument it will be equivalent to a generic CLOSEPOSITION command.

Advanced Usage

If no account is specified, but an instrument and/or market_position is provided, FLATTEN will exit all positions across all accounts that match that criteria.
