Here is a quote from Alpaca github about the historic\_agg\_v2 polygon function:

“Specify the `_from` parameter if you specify the `to` parameter since when `to` is specified `_from` is assumed to be the beginning of history. Otherwise, when you use only the `limit` or no parameters, the result is returned from the latest point.”

But, if i leave out the “\_from” or “to” parameter and just request the “limit” parameter, i get an error that says “\_from” and “to” are required parameters.

Those two `_from` and `to` are required parameters in Polygon API, so you cannot omit them.
