Step 1: API Connection
The bot connects to your exchange (Binance, Bybit, Coinbase) using API keys.
- You generate API keys on your exchange
- You paste them into 3Commas (or your bot platform)
- The bot can now read prices and place orders on your behalf
- Security: API keys should have trade permission only, NEVER withdrawal permission
Step 2: Market Monitoring
The bot continuously monitors:
- Current price of your chosen trading pair (e.g., BTC/USDT)
- Order book depth and liquidity
- Price changes over time (1-minute, 5-minute, 1-hour candles)
- Technical indicators (RSI, MACD, moving averages — if configured)
Step 3: Strategy Evaluation
The bot checks if your preset conditions are met:
| Strategy | Trigger to Buy | Trigger to Sell |
|---|---|---|
| DCA Bot | Price drops by X% from entry | Price rises by Y% (take profit) |
| Grid Bot | Price hits lower grid line | Price hits upper grid line |
| Signal Bot | TradingView alert fires | Opposite signal or TP reached |
| Futures Bot | Same as DCA + leverage | TP or stop-loss hit |
Step 4: Order Execution
When conditions are met, the bot:
Step 5: Safety Order Activation (DCA Bots)
If the price drops after your initial buy:
Step 6: Profit Taking
When the price reaches your take-profit target:

FAQ: How Crypto Bots Work
Q: Do crypto bots need my money to be sent to them?A: No. Your money stays on your exchange (Binance, Bybit). The bot only has API access to place trades. It cannot withdraw your funds if you disable withdrawal permission.
Q: How fast do crypto bots execute trades?A: Crypto bots execute trades in milliseconds via API. This is 100-1000x faster than a human clicking "buy" manually.
Q: Can a crypto bot lose all my money?A: A bot can lose money if the market crashes severely and you don't have stop-losses. However, DCA bots on spot markets cannot lose all your money — they hold the actual crypto asset, which can recover in value. Futures bots with leverage carry higher risk.
Q: Do crypto bots work on weekends?A: Yes. Crypto markets are open 24/7, unlike stock markets. Bots trade on weekends, holidays, and overnight — this is actually when they generate some of their best profits due to increased volatility.
Q: How does the bot know when to sell?A: You set the take-profit percentage when creating the bot. When the price rises by that percentage from your average entry price, the bot automatically sells. You can also enable trailing take-profit to ride trends for larger gains.
Q: What happens if the exchange goes down?A: If the exchange API is temporarily unavailable, the bot pauses and resumes when the connection is restored. Your existing positions remain on the exchange. 3Commas also has server-side redundancy.
