Sims

Computes the dollar returns of a portfolio for multiple simulated time series

This builds upon and uses /weights and /paths for computation. It takes a time-series of unlimited instruments as an input and splits it into two sets of data - a training and a simulated test set.

The training set is the first 252 days long, the remaining days are used for the test set. The training set’s mean and standard deviation is then used to generate simulated test sets, in the current case 5 test sets. The test set’s simulated prices are then used to track the portfolio performance.

The output is a JSON-formatted time-series of end-of-day portfolio performance in dollar terms for each of the 5 test sets, also addressed as “5 runs”.

note

This endpoint is experimental so please take note that the processing performance hasn't been fine tuned yet, i.e. do expect up to 30 seconds to get a response from the engine. The computation are however production ready
