Trouble-shooting cheat sheet.

API key won’t connect

• Error: “Invalid key / no permission” on 3Commas, TradeSanta, Autoview.

• Fix:

  1. Regenerate the key.

  2. Tick “Enable Spot & Margin Trading” (Binance resets this every 90 days).

  3. Paste fresh key into the bot and save.

  4. On 3Commas check My exchanges → Reconnect if status is red.

“Insufficient balance / order size too small”

• Why: Start order below the exchange minimum or wallet split across sub‑accounts.

• Fix:

  • Raise start size: Binance needs ≈ $11 per order.

  • Move funds to the trading wallet; free up margin in futures.

Webhook 400 / 401 / 500

• Why: Bad JSON or missing Autoview key.

• Fix: Put the key=YOUR_KEY text at the very start of each TradingView alert. Double‑check braces.

Bot armed, but no fills

• Kryll: launch date mis‑aligned; entry block never fires. Use Simulate Entry to test path and shift the Start block earlier.

• 3Commas Signal Bot: bot paused after error flag. Toggle bot OFF → ON; clear “Invalid API key” notice.

Back‑test looks great, live PnL stinks

• You started at a different price zone than the test. Grid/DCA need the same entry level.

• Fees and slippage not switched on in the tester. Add them, retest.

Double orders / over‑trading

• Duplicate alerts firing on every tick. Set TradingView alert to Once Per Bar Close.

• For Autoview append &C=all before new entries to flush stray limits.

Rate‑limit hits (error 429)

• Add a 250 ms sleep in Python loop or cut signal frequency.

• For 3Commas raise bot “max active deals” throttle.

Mobile push silent

• Kryll/TradeSanta/3Commas: open app, Settings → Notifications, flip Push, allow OS permissions.

Unexpected stop / bot crash

• VPS ran out of RAM or disk. Clean logs, allocate 1 GB swap.

• Check platform status page; restart session if the API outage is over.

Keep this sheet handy. Most first‑run headaches fall into one of these buckets. Solve them once, the next bot is plug‑and‑play. Most other issues can be fixed by: reading this guide and the official guides, asking ChatGPT for help or asking an experienced programmer (in the worst case scenario).

You may not succeed right away. It's ok when you fail when you try something new for the first time. Just remember that everything is fixable.
