7\. Sync Open Positions

* When backtesting, TradingView may already assume an open position.
* To stay in sync, **open the same position size in Polynomial** before the webhook triggers.

### FAQ

**1. How should I align open positions in Polynomial with my strategy?**\
You must manually establish the same position size in Polynomial that your backtest assumes. This ensures that alerts correctly reverse or modify positions rather than opening duplicate trades.

**2. Is there a sizing requirement for contracts?**\
Yes. In Polynomial, **1 TradingView Contract = 0.001 asset**. Ensure that you configure your trade size in TradingView accordingly.

**3. Are there any security steps I should follow?**\
Yes. You are required to sign a message to verify your identity before accessing the webhook body. The webhook body should be copied, stored securely, and never shared publicly, as it is protected to prevent unauthorized access.

**4. Can I use multiple strategies with different webhooks?**\
Yes. Polynomial supports multiple webhooks, each of which can be linked to a different TradingView strategy. Alternatively, you may also use the same webhook to manage trades from multiple strategies if desired.\
\
&#x35;**. Why is my trade size incorrect?**\
The most common reason is that after an alert is created, changes to the strategy settings do not automatically update the alert. To correct this, you must delete the existing alert, update the strategy settings, and then create a new alert.
