I wonder if people are really making money from trading bots as compared to those who really trade on their own without any help from bot. One will have to be paying a monthly subscription for the owners while there are some months you will be running negative particularly when there are fundamental issue.
There can be two options here,
1. Bots that you have developed on your own - you can program the bot yourself and make sure it runs properly.
2. Buying a bot - you have to trust and pay the developer. There are many devs out there with reputation. But this is a compromise they need to make.
For a speculative market the seond options leads to a lot of mental stress. The first option is also not free of mental stress but lower.
Using these bots will never guarantee your profit but only make sure you continue reading during sleep and at times when you are not in front of the device. Nothing more than that should be expected of a bot.
