My personal experience with bots started week but ended in tears that I began to think my account was been monitored.
After I got my first bot and started trading, it was seeking like a poverty crusher when I was able to raise $15 to $115 in less than 24hrs then $400 in less than three days.
However, I took nothing out of the market as everything got blown away.
Bots and their martingale can be disastrous. That's why I have learned to depend on indicators that will guide my decisions.
