A crypto trading bot is a program that analyses crypto prices, spots market trends, and executes trades on the behalf of its users. These activities usually happen automatically and largely without supervision.
These Cryptocurrency bots are usually powered by an AI algorithm or machine learning model which is used to identify profitable market conditions. When the current conditions are similar to the preprogrammed profitable model, the bot executes trades.
More advanced bots can automatically adapt to changing conditions and use technical indicators to determine whether or not a trade will be profitable in real-time. If the algorithm determines it is, the bot executes the trade, usually in a fraction of a second.
Trading bots take emotion out of the equation, allowing traders to follow set principles to increase profits and manage risks.
Trading bots analyse price data, social media sentiment, and other market data points to understand what is happening in the market. It applies indicators, which are mathematical formulas, to output signals that either signify a market change or a continuation.
It then executed trades that are most mathematically probable to be profitable based on insights obtained from its analysis.
The real catch with trading bots is that it does all the analysis and trades automatically. Once you give it a direction to go, vis-a-vis your trading strategy, it will run with the parameters you set continuously until you stop or alter it.
These bots usually come as an application that connects to the popular MT4 trading platform and as such partners with several of the crypto brokers to offer its services. When signing up, users may need to also create an account with an affiliated broker.
There are a number of different Bitcoin trading bots with each one suited to specific roles. Here are the best-known and most used types of Bitcoin trading robots:
Cryptocurrency trading bots follow a set of rules, parameters, or directive that tells them what market conditions are favourable and what to do when it spots that circumstance. These rules are called trading strategies and you’ll need to develop one before using the bot.
Below are some trading strategies you can use today:
Momentum trading involves using the strength of price movements to determine entry and exit points. The basis of this strategy is that during swings, the price starts slowly and gradually picks up speed until it reaches a plateau and begins to slow down.
The bot is programmed to detect growing momentum in the general market direction, buy close to the start of the movement, ride the wave until it begins to lose steam, and then sell.
A physical representation of the momentum movement would be a sinusoidal wave where the bot buys at the end of the previous trough and sells at the peak.
Arbitrage strategy involves profiting from market inefficiencies reflected as a difference in the price of the same asset in separate markets. For example, Bitcoin could be $20,000 on one exchange and $20,020 on another.
In this case, a trader could buy BTC for $20,000 on exchange A and sell it for $20,020 on exchange B, making a $20 profit. However, looking through exchanges for price inefficiencies can be tiresome.
A bot could constantly keep track of the prices of various assets across multiple exchanges in real time. When it spots price inefficiency in an asset, it can automatically buy the asset at a lower price and sell it at a higher price.
The mean reversion strategy assumes that the price of an asset will always come back to its average value after movements away from it in either direction. For example, if the average price of Bitcoin is $22,000, buyers will be willing to buy if its current price falls to $19,000. So also, buyers will be more likely to sell if the price rises to $28,000.
In both cases, buyer sentiment will bring the price back down or up to the average price. The calculations for the average price can be coded into the bot so it keeps an eye on the average price of crypto at all times and buys or sells depending on the current price.
The market-making strategy involves placing buy and sell orders for the same asset simultaneously in an attempt to profit from the bid-ask spread. For example, if Bitcoin’s highest bid price was $20,000 and the lowest sell price was $20,020, the bot would buy BTC for $20,000 and sell for $20,020, earning a $20 profit.
Using this strategy may require a significant amount of funds to generate reasonable profits. Whales, institutions and cash-rich players usually use this strategy.
Using a tool like a cryptocurrency trading bot for trading cryptocurrencies is considered completely legal in most jurisdictions. However, while the trading bot works like a driver for your trades, you are still considered responsible for its activity. Hence, using any kind of pump-and-dump bot is strictly against the rules. In this regard, please remember that any activity which can be considered illegal in standard trading circumstances will be considered illegal in the domain of crypto trading too.
To pick a legitimate crypto bot, you should check if it’s affiliated with one or more regulated crypto brokers. The trading platform should ideally have been approved/certified by bodies like CySEC (Cyprus Securities and Exchange Commission), ASIC (Australian Securities and Investments Commission), FCA (Financial Conduct Authority) etc. Being featured regularly on well-known media platforms as well as crypto-related forums is also a good indicator of legitimacy.
Please be aware that crypto trading bots are nothing more than software programmes. Hence, even though they are reportedly used regularly by a great multitude of crypto traders, there are no guarantees of profit.
There are also multiple risks associated with such bots and automated trading platforms. It’s important to keep in mind that these tools are geared more towards traders and not investors. However, you can still make them work well for you in generating a passive income if you know how to configure them properly.
Considering the trading volumes they are engaged in, hackers are always trying to target trading bots. Therefore, select a trading bot that is backed by a legitimate and credible team known for its security measures.
The reliability of a cryptocurrency trading bot is very critical to its profit-making ability. It should enable you to continue trading 24/7. You must check independent reviews and ensure that the bot doesn’t suffer from frequent glitches.
Most bots have a minimum deposit requirement. Ensure that it is within your range of affordability. Also, find out how long withdrawals take and if there are minimum withdrawal limits.
Before signing up with a bot, ensure it offers services to people in your geographical area. Also, check whether or not it trades the underlying crypto or just the CFD. If it only trades the CFD, ensure retail traders are legally allowed to trade CFDs in your area.
Claimed success rates should not be taken at face value as many of them are best-case scenarios. However, the bot should be able to consistently generate reasonable profits.
Most traders, irrespective of how seasoned they may be, prefer bots that have an intuitive interface, suiting their expertise level. In essence, it should fall in line with your trading strategies and the customisation level you require.
While some crypto trading bots can be used freely, others can have a significant price tag attached to them. It is generally observed that a paid-for bot provides better service and superior features. Having said that, you must always ensure that you are getting the complete worth of your investment. Some bots will offer free trials.
Different bots charge different trading fees, always check. Those trading bots that work on top of major cryptocurrency exchanges may also have additional fees from the exchange.
Another important consideration is the customer support accompanying the trading bot. You should check how its updates are rolled-out and if bugs are resolved in a timely and efficient way. Ideally, the tool should also come with its training modules and videos to help the new users.
To open an account, you’ll first need basic information like an email address, a phone number, and your name. When you click Continue, you may be asked to input your birthday as the law only allows legal adults to access certain services. Some bots work with crypto brokers so you may also be directed to open an account with one of them.
In keeping with the law, you’ll need to pass KYC verification by submitting documents that verify your ID and where you live. A government-issued ID and proof of address documents like a bank statement or utility bill should be sufficient. Depending on the bot provider, you may also be asked for proof of funds like a bank statement.
Next, you’ll need to deposit funds into the trading account with your broker. Most of the bots on our list support various funding methods like credit cards, bank transfers, and PayPal. Also, the consensus on the minimum deposit is $250/€250. Most bots do not charge a deposit fee, however, refer to our comparison table above to be sure.
On a fundamental level, developing a trading strategy means setting trade parameters like entry levels, exit levels, and stop losses. The entry level is the price you want the bot to enter a trade. The exit level is the price you want the bot to exit a winning trade, while the stop loss is the price you want the bot to close a losing trade.
As you become more proficient, you’ll be able to develop more sophisticated strategies that use complex indicators.
This step is more of a support. After the bot has executed your trade, you can monitor it to ensure it executes trades as you want it to and that your strategy is profitable.
Firstly, we tested and traded each Bitcoin robot bot in different market conditions and at different times of the day. This was so we could both quantitatively and qualitatively assess each robot's profit-making capabilities.
To achieve our results and make the selection of our top picks, we trialled each Bitcoin robot in isolation and also across a number of different timeframes. To get accurate results faster we chose lower timeframes including the five minute and one minute price charts. This provided us with more rapid and relevant feedback than we would otherwise have got running the bots on anything above the 30-minute timeframe.
Having done this, we then compared the results to assess where each of the Bitcoin bot’s strengths and weaknesses lay. In total, we tested more than 20 crypto trading robots to find our top 6 best bot picks.
Trading bots provide a level playing ground for retail traders to compete in the volatile and increasingly automated crypto market. They are powered by AI and machine learning algorithms that scan market data, spot patterns and relationships and make predictions based on these relationships.
Most bots come as web-based browser applications that connect to an MT4 trading terminal offered by a broker. As such, they partner with global brokers to offer their services to users around the world.
To get started, visit the website of a bot of your choice and sign up using your full name, email address, and phone number. Some bots may ask you to verify your identity and address, an ID and utility bill should be sufficient.
Always check your bot’s minimum deposit requirement before signing up, usually around $250 for most bots we came across, and their supported payment methods. If it all sits well with you, go ahead and deposit.
Bots usually come with customer service teams that help with any trouble you may run into. Some teams work 24/7 while others only work 5 days a week.
