A crypto trading bot is just software that does four things, over and over, without getting tired or emotional: it watches the market, decides, places the order, and manages the trade. Here's what actually happens under the hood — no jargon.
The Four-Step Loop
Strip away the marketing and every trading bot does the same cycle: watch the market, decide whether to act, execute the order, then manage the position until it closes. It repeats this 24/7.
Because it's software, it does this identically every time — no fear, no FOMO, no walking away from the screen at the wrong moment.
1. The Signal: Deciding When to Act
The bot reads price data and applies a strategy to decide if conditions are right. A common, transparent approach is an EMA crossover with a trend filter: it only buys when a fast moving average crosses above a slow one and price is above a longer-term trend line.
Prometheus adds a live signal-strength meter so you can watch a trade forming — it fires an early alert as conditions line up, before it acts.
Let the bots trade while you don't

When the signal triggers, the bot calculates a position size and sends the order to your exchange through its API — the same way the exchange's own app places orders, just automated.
Crucially, the size isn't random. A well-built bot sizes the trade from the stop distance so that a losing trade costs a fixed, small percentage of the account.
3. Managing the Trade (The Part Humans Skip)
Once in a trade, the bot places a stop-loss and a take-profit immediately — a “bracket” around the position. It can trail the stop, take partial profit, and close on exit signals, all without hesitation.
This is where automation earns its keep: the discipline to cut a loser and let a winner run is exactly what emotion breaks in manual trading.
So Where Does the “AI” Fit?
“AI” in trading bots usually means the software recognizes patterns and adapts to conditions — filtering out low-quality setups, skipping high-impact news, and pausing in bad conditions — rather than blindly following one rule.
It's a tool for consistency, not a crystal ball. No bot, AI or otherwise, can predict the market. What it can do is execute a disciplined plan perfectly, every time.
