In general, no one recommends the use of bot software.
What is the logic of the running bot software? Can we add our own trading algorithms to these software?
It's not really that hard to understand , the bot simply makes thing automatic without the need of you doing anything. If you don't know anything about trading or how It works then It's not a good idea to buy one or use it.
Algorithms are actually made by the creator of the software and paid bots logically have closed source codes so without the source code Its impossible to add anything .
