Seconded, this EA isn't about fireworks, it's about results. Tradingshed, based on your chart, you actually have very good wins.
You want the robot's logic to enter with high probability trades...not gambling. The point is to set it and forget it. Pick a risk setting and leave it. Evaluate performance after several months and adjust your risk as desired.
Here's something to chew on, Avg 10% growth per month may not seem like much unless you consider the wonderful compounding affect. After a year, your account will have doubled. If your broker has good price feeds and low spreads, you should do well. BHS's 10 to 15 trades a month is a good barometer.
If you get less than that, check for any problems or change brokers.
