[Feature Request] Add the SMA1000

[egofer]

Is your feature request related to a problem? Please describe. The 1000-day moving average (ca. 4 years) is widely used in long-term investment strategies, becouse it allows characterisation of trends at the top and bottom of the market. Many buy and hold investors consider this moving average as one of the factors to consider when entering a new position.

Currently Portfolio Perfomance does not allow the user to set the periods of the simple moving average (SMA), with the highest default value being 200 most recent trading days (sessions).

Describe the solution you'd like Allow the historical price chart to include the SMA1000 as is currently the case with the SMA200, SMA100, SMA50, etc.

Describe alternatives you've considered Preferably, allow the user to define the desired SMA/EMA intervals or alternatively include the SMA1000 as an eligible value when configuring the chart.

Additional context This feature request is closely related to PR #2503.
