It is a little more mature than my previous efforts. It uses limit orders to overcome slippage problems. There's a lot rounder included. It should not attempt to invest too much in low dollar volume stocks. It includes code to remove cash from the amount available when you place an order, even when the order hasn't filled yet as that is likely what your broker does. It is still beta so by all means point out any bugs or problems you may find.

There's a nasty downturn in 2015 that I suspect might be due to other algos, any thoughts on this?
