# Troubleshooting

If you encounter issues while using the AstraAlgo Backtester on TradingView, this guide provides solutions to the most common problems. 

Review the points below before reaching out to support to ensure a quick resolution.

<details>

<summary><strong>No Signals Displayed</strong></summary>

Check your Signal Mode in the settings menu. If set to “Off,” signals will not appear.&#x20;

Also confirm that filters such as Session, Noise, or Volatility are not blocking signals during the selected time period.

</details>

<details>

<summary><strong>Backtester Not Loading</strong></summary>

Refresh your TradingView chart and ensure your [subscription is active](https://docs.astraalgo.com/getting-started/onboarding/gaining-access-to-our-toolkit).&#x20;

If the indicator is already applied, try removing and reapplying it to resolve loading issues.

</details>

<details>

<summary><strong>Alerts Not Triggering</strong></summary>

Make sure alerts are set to “[Once Per Bar Close](https://docs.astraalgo.com/resources/materials/alerts-reference)” to receive confirmed signals.&#x20;

Also check that you have selected the correct alert condition and that any session or time zone filters are properly configured.

</details>

<details>

<summary><strong>Unexpected Results or Missing Trades</strong></summary>

Review your filter settings and signal parameters, as overly strict filters or misaligned percentages can exclude trades.&#x20;

Remember that backtests may differ slightly across timeframes due to TradingView’s historical data handling.
