Just like in poker, you need to know when to turn of your bot when your daily target has been reached or nearly reached. I have manual control when to turn on or off the bot at my will. This all comes down probability and measuring your risk in your log for the day. During my webinar last nite, someone asked why they fail in forex after 12 years.

With out it, you are not able to quantify the probability of when to shut down your bot for the day if you feel close in achieving max performance.
