The bot must be bulletproof, by this I mean that it does not matter what happens, the bot should present no bugs or weird behavior, lets be honest the most scary thing about a bot is that you are letting a few lines of code to dictate your financial future, however unlike regular code, in which a mistake is for the most part irrelevant and you can always improve it after the fact.
When it comes to your bot a single bug can cost you so much money that it would be unrealistic to think you will ever recover it, so the bot must present no such bugs at all, and for that you will need extensive testing and the ability to imagine almost any scenario possible so the bot can deal with it.
This must be the dream of all but I'm sorry that it is not possible and there are no perfect software yet up to date. This is why they always roll an update from time to time to fix the bugs that a software will encounter. The more it won't be possible because the guy seem to be learning yet despite being successful with some of his projects.
Without a bot, we are always advice to use small amounts but with a bot, we need to follow this strictly because a bug can ruin our trades and lose all our money quickly. A really good bot can only experience it rarely but losing is still there because of the unpredictability of the market and the coin that we choose to trade.
And that is my point, creating a piece of software that trades in the exact same way as you do, that has no bugs and does this without taking any break is the objective of most traders.
But that ideal is almost impossible to reach, so in my opinion at most a bot should give signals, but it should not have the feature of trading by itself, this way the trader can always double check that everything is in order and only then conduct a trade on the exchange of their preference.
