I want to use SymbolicRegression.jl to analyze stock market data. Specifically, I need to design a rolling operator to process time series data, similar to rolling_sum in pandas. The input of this operator consists of time series data, the window size, and the sliding stride required for rolling. How can I design such an operator for SymbolicRegression.jl?

By input to the operator, do you mean input to the expression?
You can learn expressions over time series without extra effort by simply repeating/reshaping your time series data to have shape:
(window_size * num_features, num_examples)
if you have three variables in your time series say xy and z, and your window size is 2, then you would have features x_1, y_1, z_1, x_2, y_2, z_2 - where x_2 is simply the previous value of x.
