# Troubleshooting

### Strategy validation failed

Common causes:

* Missing **Market Data**.
* No **Buy Order** or **Sell Order**.
* Required inputs are missing (example: OB without Swing Highs/Lows).
* Disconnected branches.

Fix:

* Start at Market Data.
* Follow every connection to an action.
* Check node requirements in [Node reference](https://docs.quantbytes.net/bot-studio/node-reference).

### Backtest ran but no trades

* Conditions are too strict.
* Compare operator/value mismatch.
* Crossovers never happen in the selected date range.

Fix:

* Logically relax one condition.
* Test on a longer date range.
* Verify indicator ranges (example: RSI is 0–100).

### Wrong trading direction

* Check which order nodes exist.
* Use manual override in backtesting if needed.

### Getting help

* Capture the exact error message.
* Screenshot the graph and properties panel.
* Include symbol, timeframe, and date range.
