For those who are just thinking about a bot

Most of those who work with crypto have probably considered proposals for trading bots or, if you have technical skills, have planned its algorithm and further implementation. I think that those who are able to build a bot themselves are an absolute minority. Who can allocate a budget to develop such a program - a lot. And, given the offers from services that provide such bots for rent, every trader or investor can have a bot.


But this is not about the program at all. What is a program? A set of algorithms with a focus on specifics. The most important thing in the bot is the trading algorithm. And only having such an algorithm, after a lot of closed trades manually, only then you can switch to the bot.
Many people believe that the bot is a magical program in which you need to invest a little of your working capital, and then it will lay golden eggs. No, that's not true at all. Only successful hand trading needs to evolve into running a bot, i.e., automation.
What does the bot do? It buys according to the rule, tracks the rate, sells according to the rule. Plus technical nuances like BNB balance tracking for reduced commission, balance check, compliance with regulations on the size of the purchase (tickSize and minQuality) of a particular coin. 
Naturally, the bot must be taught to analyze the current state of trading on a particular pair, but the program does not generate the algorithms of analysis by itself, but acts in accordance with the algorithm the programmer puts into it according to the technical requirements.
The real schemes, which work reliably, are not put in the public domain. This means that you must either develop your own scheme, or use some service, but with the analysis of its strategy and the timely cessation of trading.
Collapses happen all the time, it's important to understand when to stop trading. 
On the other hand, the use of third-party bots will give you good experience, at what moments the strategy does not work and then already think about what preceded it.
