# Max Positions

The filter for `max_positions` allowed blocks signals based on the maximum number of allowed positions per account. 

### Example Payload

Assume you have open contracts in ES 06-26 and NQ 06-26. If a PLACE order signal arrives for a third instrument with `max_positions=2;`, for example, the signal will be blocked because no more than 2 positions can be open in the account at one time.

> key=your-secret-key;\
> command=place;\
> account=sim101;\
> **instrument=CL 4-26;**\
> action=buy;\
> qty=1;\
> order\_type=market;\
> tif=day;\
> **max\_positions=2;**

Valid values for `max_positions` are any integer value greater than zero.
