What is a trading bot? Definition and how it works

A trading bot is a program that opens and closes trades in your brokerage account based on pre-defined rules. It monitors market conditions to see if they meet those rules and, when they do, it executes the order without you needing to be at your screen. What it doesn't do is predict where the price will go; it simply executes a strategy that you or a team designed beforehand.

What a trading bot does inside your account

A trading bot's work boils down to five tasks, always the same and always in the same order:

1. Monitor the market. Continuously reads prices and other data.
2. Compare against its rules. Checks if current conditions match the strategy.
3. Calculate trade size. Decides how much volume to move based on account capital.
4. Send the order. Opens the position with its stop loss and take profit.
5. Close and record. The trade ends when it hits one of those levels or when the strategy dictates, and it is recorded in the broker's history.

There are two ways to connect to your account. With MetaTrader, the bot sends orders directly to the platform. With copy trading, the account replicates the strategy's trades within the broker itself. Boosty works with one or the other depending on the broker, and neither allows the bot to touch your withdrawals.

From a rule script to a system with continuous analysis

Very different tools coexist under the name "trading bot." The difference lies in how much they decide and who maintains them:

A simple script is easy to understand and audit, but it stops working as soon as market behavior changes. A system with continuous analysis adapts better, at the cost of depending on someone to maintain it. Before using any bot, the useful question is which of these three groups it belongs to and who is responsible for it.

What gets mistaken for a trading bot

Several services present themselves as "automatic" without being fully so. They are distinguished by who executes the trade and where the money is located:

The last row is the one that deserves the most caution. When money leaves an account in your name, the risk is no longer just market-related.

What does the bot decide, and what does the team behind it decide?

A bot does not invent its strategy or change it on its own. Decisions are divided into three levels:

• The bot decides whether current conditions match the rules, the size of each trade, and when to close a position upon hitting its stop loss or take profit.
• The team decides the strategy, the parameters, and any changes when market behavior shifts. At Boosty, the strategy has over eight years of history, and a team of traders adapts it whenever the market enters a different phase.
• You decide how much capital to invest, which broker to use, and when to disconnect the system.

A common question among new members of the Boosty Telegram group illustrates this division well. Many ask if all users share the same stop loss. The signals are the same, but each account trades with a size proportional to its balance, so the amount at risk is around 1% of available capital. The strategy is shared, but the sizing is individual.

This teamwork comes at a cost, even if the software itself isn't charged for. We explain how a bot that isn't sold is financed in free trading robots.

What a trading bot cannot do

Automating execution has clear limits:

• It does not predict the market. It reacts to conditions that are already occurring.
• It does not improve a bad strategy. It executes it with more discipline, even when losing.
• It does not avoid price gaps. News or the Monday market open can close a trade at a worse price than the one set.
• It does not decide how much you can risk. That figure depends on your situation and can only be set by you.

Trading Forex carries a real risk of losing capital, whether you use a bot or not.

What a trading bot is and what to check before connecting one

A trading bot is a program that executes a pre-designed strategy within your account. They range from single-rule scripts to systems maintained by a team, and the practical difference lies in who makes the decisions and who handles the maintenance.

Before connecting one, confirm that the deposit remains in your name at the broker and that you understand which part of the decision-making process remains yours.
