# FAQ & Troubleshoot {% hint style="info" %} **Tip:** For instant assistance try the live-chat widget on our website—it solves \~90 % of questions in under a minute. {% endhint %} *** **1 Indicator not showing up — username mismatch** * The TradingView **username** you entered at checkout must match the one you are logged in with now. * Find the name on your invoice email or in TradingView **Profile → Settings → Username**. * If they differ, email **** with the correct username and we'll update your licence. *** **2 Red lock icon next to the script — script still locked** * 90 % of the time the username is wrong or the purchase isn't finished. * Enter the correct username (see Q 1), wait 30 s, then reload the chart. * When the lock turns **green**, the script is ready to load (see Q 3). *** **3 How do I unlock the indicator?** * A **green lock** means the licence is recognised. * Click the script name under **Invite-only Scripts** to add it to the chart. * If the lock stays red, go back to Q 2. *** **4 Indicator timeout error** * TradingView shows timeout when calculations take too long (usually on lower timeframes or with AI enabled). * **Quick fix:** Open settings (⚙️) → toggle any input → click OK. This forces a refresh. * **Alternative:** Remove the indicator (×) and re-add from **Invite-only Scripts**. * Consider using **Static** mode or higher **Update Frequency** if using AI optimization. *** **5 Cannot load – "Too many indicators"** * TradingView limits active indicators per chart: * Free = 2 Essential = 5 Plus = 10 Premium = 25 Expert = 30 Ultimate = 50 * Remove unused indicators (× in the legend) and reload, or upgrade your plan/split across multiple charts. *** **6 Open the indicator settings** * Click the **gear (⚙️)** icon next to the script name in the legend. * All inputs, colours and alert toggles are here. * **Reset to Default** is bottom-left inside that window (see Q 12). *** **7 "Study Not Auth" error** * The script could not verify your licence. * Refresh the page (F5)—fixes \~30 % of cases. * Re-check username spelling (Q 1). * Occasionally TradingView's auth server is busy; wait a few minutes and reload. * Still failing? Send a screenshot and your username to support. *** **8 "Internal Server Study Error"** * Temporary TradingView server issue or cached script. * Hard-refresh (**Ctrl + Shift + R**) or open a new tab / the desktop app. * Check [**https://status.tradingview.com/**](https://status.tradingview.com/)—if components are red, wait for green. *** **9 TradingView asks me to pay again** * It's a quota notice, **not** a payment request. * You've reached your indicator limit (see Q 5). * Remove one script or upgrade your TradingView plan; the prompt disappears. *** **10 Does the indicator repaint?** * **No.** Once a bar closes, its signals and values never change. * Values can "breathe" while the current bar is still forming—normal for any real-time calculation. *** **11 How do I get the latest version?** * Updates are pushed automatically. * If you boosted the script you'll receive an email titled **"Infinity Algo – new version."** * Remove the old copy and re-add it from **Invite-only Scripts** to load the newest build. * Existing alert templates stay intact unless TradingView flags an input change. *** **12 Reset settings to factory defaults** * Open settings (⚙️) → **Reset to Default Inputs** → OK. * Colours can be reset under the **Style** tab. *** **13 My alerts don't fire** **Quick checklist** 1. Alert created on the **correct indicator version**? 2. **Condition** set to **Once per bar close** (recommended). 3. Alert quota: Free = 3 Essential = 20 Plus = 100 Premium = 400 Expert = 600 Ultimate = 1 000 4. Browser tab closed? Use TradingView desktop or server-side alerts (paid plans). 5. Follow the step-by-step alert guide in the docs. *** **14 No backtest data for futures** * Futures require a different order size setting in TradingView. * **Fix:** Open settings (⚙️) → **Properties** → change **Order Size** from "USD" to **"Contracts"** or **"Quantity"**. * This applies to all futures symbols: ES, MES, NQ, MNQ, YM, RTY, CL, GC, etc. * Futures trade in contracts/lots, not USD position sizing. *** **15 Remove the indicator from a chart** * In the legend click the × next to the script name. * The licence remains in **Invite-only Scripts**—you can re-add it any time. *** **16 What are the optimal settings?** * **Optimal settings** vary by market, timeframe, and trading style. Utilize our **backtesting** to discover what works **best** for you. *** **17 Can I change my TradingView username after purchase?** * Yes, email with your new username. One free change per license. *** **18 Can I share my indicator with others?** * **No.** The license is tied to your specific **TradingView username** and is non-transferable. *** **19 Still need help?** * **Live chat** – bottom-right of our site (fastest). * **Email** – (responses within 24 h on business days). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
