EA only entered 1 trade over 2 years data

[J Webster]

This EA in the tester only entered 1 trade in over 2 years worth of data.

Any ideas why? It's based on the alligator indicator and when the green line moves below the red line or vice versa, it should enter a trade. All trade closes are handled by the stop loss, which is modified at regular intervals.
