Test the EA using the MetaTrader Strategy Tester.  Test over the last 1 month and determine how many trades there are over that time period.  This can give you an idea of how many trades per day you should get on average.

You can also add the indicators to the chart and identify the points on the indicators that should trigger an Entry and then determine if an Entry was actually applied to the price chart.
