What is an AI trading bot? How they work and what to check

What an AI trading bot is

A trading bot is software that places trades for you. It watches the market, checks whether its rules are met, and sends buy and sell orders to your exchange account, around the clock and without getting tired or emotional.

An AI trading bot adds artificial intelligence somewhere in that chain. The phrase is used loosely, so it helps to ask exactly where the AI sits, because that decides how much you can trust the bot.

Three places AI can sit in a trading bot

1. AI writes the rules. You describe a strategy in plain words, and a language model turns it into precise rules: what to buy, when, how much, and when to sell. You confirm the rules, and ordinary software runs them.
2. AI decides the trades. A model looks at the market and decides each buy and sell itself, often in ways no one can fully explain.
3. AI explains what happened. After each trade, AI writes a plain-language reason: which rule triggered, at what price, and why the bot stayed out at other times.

The first and third are about understanding. The second is about prediction, and it is where most of the risk and most of the marketing hype sit. A bot whose AI decides every order is only as safe as the limits around it, and you cannot easily check its reasoning.

TradeCorgi uses AI for the first and third, never the second. The language model drafts your strategy card and explains each trade. A rules engine with no AI in it places orders, and only the version you confirmed.

How a trading bot turns rules into orders

1. Market data arrives. The bot reads prices from the exchange, at intervals ranging from milliseconds to minutes.
2. Rules are checked. "Has BTC fallen 5% within 24 hours?" "Is an open position 4% above its buy price?"
3. Limits are checked. A careful bot asks: is there budget left, is the daily loss limit intact, are there fewer than the maximum open positions?
4. An order is placed. The bot sends a buy or sell order through an exchange API key.
5. The result is recorded, ideally with the reason.

Step 3 is the one many bots skip or leave optional. It is the most important step for your money.

The kinds of crypto bots you will meet

• Grid bots place a ladder of buy and sell orders across a price range and profit from swings inside it, losing when the price leaves the range.
• DCA bots buy a fixed amount on a schedule.
• Dip and rebound bots buy after sharp falls and sell on a set rebound.
• Indicator bots act on levels such as RSI or moving averages.
• AI agents take instructions in plain language and may combine any of the above. Read more in what is an AI trading agent.

Many exchanges give simple grid and DCA bots away for free. What you pay for in a better product is testing, limits and explanation.

Five things to check before you trust one

1. Who decides each order? Your confirmed rules, or a model you cannot inspect?
2. What limits does it enforce, and how? Look for a budget, a stop-loss, a daily loss limit and a cap on open positions, enforced in code before every order, not as a suggestion.
3. Can it withdraw your money? It should only accept exchange keys that can trade but not withdraw.
4. Can you stop it instantly? One tap should pause it, and ideally sell its open positions.
5. Are its backtests honest? Results should include fees and slippage, state the period, show the worst drop and compare with holding the coin.

If a bot promises returns, shows results without a period, or asks for keys with withdrawal permission, walk away.

A worked example

You type: "Buy $50 of BTC when it drops 5% in a day. Sell at +4%, stop at -6%." Your Corgi asks for the one missing piece, a daily loss limit, and you choose $25. The strategy card now reads: entry on a 5% fall within 24 hours, $50 per buy with at most 2 open, exit at 4% above the buy, stop at 6% below, $25 daily loss limit.

You confirm the card. The backtest runs with Binance's fees, and a paper agent starts on live prices. When BTC falls 5.3% overnight, the agent checks its limits, buys $50 of BTC on paper, and writes: "Bought $50 of BTC at $86,930. BTC fell 5.3% in 24 hours (entry rule). 1 of 2 buys open." This is an illustrative example, not a real result.

Where AI trading bots fall short

• They do not make a losing strategy win. A bot follows rules faithfully, including bad ones.
• They cannot predict prices. Claims otherwise are a warning sign.
• They depend on the exchange. Outages, maintenance and key problems happen, so a good bot pauses safely and tells you why.
• Fees add up. A bot that trades constantly can lose to fees alone.

A checklist before you connect money

• The bot's rules are written down and you confirmed them.
• The backtest includes fees and slippage, with a stated period and worst drop.
• You ran it on paper first.
• Your exchange key is trade-only, with withdrawals off and IP whitelisting on.
• A budget, stop-loss and daily loss limit are set and enforced.
• You know how to stop it with one tap.
