feat: Adding filled_at information to trading.models.Position

[agram20]

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe.

I need to be able to re-boot my application at times and if I have open positions need to bring them back to a relevant state. trading.get_all_positions() provides most of the information I need, but in order to calculate a positions p/l I need to know how long it has been opened i.e. margin fees

Describe the solution you'd like.

add trading.models.Position.filled_at attribute so that I can determine when a position was opened

Describe an alternate solution.

@agram20 Thank you for the request. At a glance, Alpaca Trading API currently returns aggregated positions from the positions endpoints. Therefore, to construct those information, it might be required gathering info from list of orders (filling date and qty) or account activity (not implemented in alpaca-py yet #232).

Gotcha. That'll work for what I need

Might be cool if the position objects maintained a sort of memory of their lifecycle i.e. if part of a position was removed or added to at some point, not like you don't have enough other things going on :) Thanks for the direction!
