Is OnExecutionUpdate exlcusive for each strategy?

[rjm1903]

Hi,

Does OnExecutionUpdate only run based on executions for that specific strategy? Or will it run if there is an execution for another strategy that I have simultaneously running? For example, if I have two strategies running on the same asset, and the first strategy takes an entry while the second strategy is flat. Let's say that this first strategy entry hits stop loss, will this stop loss execution cause for code pertaining to stop losses in OnExecutionUpdate in the second strategy to run?

My main reason for asking is because if I have a rule in my second strategy that prevents entries in the same direction after the previous trade was a stop loss, I need to know if stop loss executions on the same asset will cause issues even if it is a completely different strategy with different code. Ideally, I would like for the OnExecutionUpdate to not interfere with eachother across strategies but I'm guessing there is a workaround if the OnExecutionUpdate does still run based on outside strategy executions.

Thank you for your help on this!

A different Strategy is a different object.

Each Strategy object's methods are completely independent,
and called independently, of every other Strategy object.

Even if you start the same Strategy twice, the two different
Strategy objects don't know about each other internally and
never interfere with the calling of each other's methods.

Any rules to 'prevent entries in the same direction' is specific
to that Strategy object. Eg, the 2nd Strategy object can only
know about the 1st Strategy object's rule 'has been
engaged' if you write your own very specific logic to
make each Strategy aware of the other.

That is, by default, a Strategy object never talks to another
Strategy object. I mean, each Strategy object is completely
independent and unaware of any other Strategy objects,
whether they running or disabled.

Just my 2˘.

Hello,

bltdavid is correct.

The OnExecutionUpdate() method called in one strategy will be independent and not affect OnExecutionUpdate() called in a different strategy.
