Butter Bot's back-testing capabilities are great, but the results are optimised for USD which can make it difficult to compare to a buy-hold strategy.

I've put together a simulation which mimics Butter Bot's trading strategy to hopefully give everyone a better idea of 2 things:

• The "best" short and long EMA parameters
• The actual increases you would have seen versus buy-hold

Thus far I've only run the simulation on btc-e trades. The 1 min trade frequency simulations take a long time to complete and given my Macbook wasn't a particularly willing participant with the other simulations they're not included.

Essentially every possible combination of short/long EMA between 1-120 are included. Thresholds and tick offset have been fixed to the recommended values.

The results are contained in a number of CSV files with short EMA vertical and long EMA horizontal. The results are BTC optimised given 1BTC was invested at the start of the period. ie. a value of 1.9 means you invested 1BTC and had 1.9BTC (or USD equivalent) at the end. This is also what your return would have seen versus buy-hold.

Check out the results and enjoy
