Identifying changes of a Futures position using Websockets

API Spot/Margin API
1

Hi,

I was attempting to identify changes to Future’s positions using Websockets.

  1. I am trying to record changes to the Position. To do this, should I only log changes that have a pa > 0 for the positions listed under “P”? For example, down below (in the record listing), there are 3 entries listed under “P”. Only one of them has a pa> 0 Why are these other 2 records (under “P”) listed even when they have amounts = 0? What is the purpose of the fields “cr”?

  2. I am also trying to determine when the position is closed. What rules can I follow to make sure I do this correctly?

Any help, hints or advice on how to do this would be greatly appreciated.

You need to confirm your position mode using GET /fapi/v1/positionSide/dual; If it’s ‘one-way’ (dual is false), check the ‘pa’ in ‘ps’ == ‘BOTH’; otherwise you’d need to check ‘LONG’ and ‘SHORT’ pa; ‘cr’ means accumulated realized profit

If you understand me in your first question, this shouldn’t be hard

Thanks for the response - I was also looking for what each of the fields mean (as it is not so obvious to me):

Does “wb” mean “writing before”
Does “cw” mean “current work”
Does “cr” mean “credit”
Of course, “s” obviously means “symbol”

???

Any help, hints or advice would be appreciated.

TIA

wb":“94.90282656”,
“cw”:“93.71241461”
“s”:“ETHUSDT”,
“pa”:“0”,
“ep”:“0.00000”,
“cr”:"-0.00057000",
“up”:“0”,
“mt”:“isolated”,
“iw”:“0”,
“ps”:“BOTH” // BOTH position always be pushed.

I am seeing the information here:

OK, never mind. I found it here:
