If so how would I adjust? I have googled a few references for the error, but the solution is not clear to me. https://stackoverflow.com/questions/32369737/error-invalid-time-series-parameters-specified-in-backtesting-r-script http://r.789695.n4.nabble.com/How-to-setup-the-tsp-attribute-of-a-dataset-td908269.html Thanks for any advice.
