Best way to determine market position?

[westofpluto]

What is the best way to determine and save current market position from within a strategy? Suppose in my strategy class I have a protected varaible:

protected MarketPosition currentMarketPosition;

Then it looks like I have several options:

1. in OnBarUpdate I can use

this.currentMarketPosition = Position.MarketPosition;

2. Or, i can implement OnPositionUpdate. I think (but I'm not sure) that OnPositionUpdate passes the current market position in:

protected override void OnPositionUpdate(Cbi.Position position, double averagePrice, int quantity, MarketPosition marketPosition)
{
this.currentMarketPosition = marketPosition;
}

Is there any advantage or disadvantage of using either of these? Is my understanding correct that both will work?

Hello westofpluto,

Thank you for your post.

Position contains position-related information pertaining to a strategy and already holds the current market position in .MarketPosition. That being said, it is not necessary to save the current market position to a variable since we can access the strategy's current market position by calling Position.MarketPosition.

I have attached a help guide link below for more information.

OnPositionUpdate is driven by Position update events and updates the account position (PositionAccount). OnPositionUpdate should not necessarily be considered for a change in strategy position. if you would like to get the current position of an account, you may use AccountPosition.MarketPosition.

Here is a help guide link for more information.

OnExecutionUpdate is driven by Execution events and updates the strategy position (Position). If you want to get the current market position of a strategy the moment an order is filled you could call Position.MarketPosition in OnExecutionUpdate.

Please review the help guide link below for more information about OnExecutionUpdate.
