The way they do it is by continually monitoring the market and reacting according to a set of predetermined rules.
They get their data from the previous data of other users.

I don't know their strategy but it must work somehow, as they keep doing it. They use the API the exchanges provide to get the data and post the order. The only way to front run them is using another bot.

Here is a suggestion:go to www.wikijob.uk▶cryptocurrency to explore possibilities to learn about creating your own algorythms.

i just think they're setting it up follow your action and your account, so they can predict somehow what's your next move base on up and down of market.

Honestly I would stay away from bots, the majority of one's you can buy online have to be set up by yourself, and if you don't know what you're doing then it's set to fail. If you want to learn how to trade properly by analysing price patterns then I know a guy who has a very simple way of doing it and he makes a lot of money. https://www.thepatterntrader.com/
I cant speak more highly of this guy, he's very genuine and walks you through his methods step by step.

There are several strategies that trading bots operate on
№1 Return to the average value
The strategy of returning to the average value is based on a simple assumption – if the price of a coin moves away from its average value, it will eventually return to it. This assumption is true for both traditional markets and cryptocurrencies. The reason for this is related to the general psychology of the market.

№ 2 Trading by momentum
An investor using this strategy estimates the ebb and flow of the market by its momentum. The ideal scenario is to ride the positive wave with your assets and sell them when the momentum reverses. The basic philosophy behind this strategy is based on the belief that asset prices will rise above the average, and then the momentum will run out, and they will fall down. In this situation, the time of buying and selling is crucial.

№3 Cryptocurrency Arbitration
The price of the same asset on different exchanges may vary. This is mainly due to the fragmentation of prices in different markets. For example, X may be worth $ 1.01 on Exchange A and $ 1.02 on Exchange B.

With the help of an arbitrage strategy, you can make a profit by buying and selling on two exchanges at the same time. To take advantage of these price differences, you will need to buy and sell X almost simultaneously.

№ 4 Naive Bayes Classifier (Naïve Bayes)
The Naïve Bayes trading algorithm uses machine learning to determine the probability of an event occurring. By providing relevant information to your bots, you help determine the correct entry and exit times.

№ 5 natural language Processing (Natural Language Processing, NLP)
In the cryptocurrency market, the price of an asset can vary greatly depending on fundamental news, such as articles, social media posts, and other content. Using NLP programming, you can teach your bots to programmatically interpret words and phrases, as well as analyze the underlying moods. For example, news about partnership agreements is usually quite optimistic.
