I have developed an algorithm / model that predicts the next day direction of CBOT wheat futures. It performs sufficiently well in backtesting that I'm interested to see how it would perform with real money behind it.
However, I'm on a pretty tight budget.
What are the most cost efficient options for front testing a strategy on a low budget? I've looked into ETF's, but often the fees involved, if reasonable for larger investments, completely obliterate any performance achieved by my model.
