Retrieve the Highest Price in X Minutes for Real-Time Analysis

The RTI_HighestPrice_in_X_Mins function in MarketXLS helps you capture the highest price of a given stock symbol within the last specified number of minutes—in real time. This functionality can be particularly useful for intraday traders who want to monitor short-term price surges or breakouts and react quickly to market changes right inside Excel.

Why Use This Function?

• Track local intraday highs for short-term strategies.
• React quickly to potential breakout opportunities in real time.
• Combine with other technical indicators to craft dynamic, rules-based trading or alert systems.
• Simplify real-time data monitoring with direct access in Excel.
• Suitable for day traders and scalpers looking for minute-by-minute market data.

How to Use in Excel

=RTI_HighestPrice_in_X_Mins(symbol, minutesAgo)

1. Enter the symbol of the stock whose price you want to analyze (e.g., "AAPL" for Apple).
2. Specify the number of minutes to look back (e.g., 10 for the last 10 minutes).
3. Press Enter to see the highest price within that recent time window.

Make sure you have a valid MarketXLS license and at least one real-time data seller (such as Zerodha or AngelOne) correctly configured before using this function.

Parameters Explained

Example Usage

Basic Examples

1. Highest Price in the Last 10 Minutes
   =RTI_HighestPrice_in_X_Mins("AAPL", 10)
   This returns Apple’s highest price in the last 10 minutes of trading.

2. Highest Price in the Last 1 Minute
   =RTI_HighestPrice_in_X_Mins("MSFT", 1)
   This quickly shows Microsoft’s high over the immediately preceding minute—useful for very active intraday strategies.

3. Highest Price in the Last 30 Minutes
   =RTI_HighestPrice_in_X_Mins("GOOG", 30)
   Ideal if you want a slightly broader intraday window for capturing a local high point.

Advanced Scenarios

• Intraday Breakout Detection
Combine RTI_HighestPrice_in_X_Mins with other RTI_ functions (like RTI_LowestPrice_in_X_Mins or RTI_PriceChange_X_Min_Ago) to detect potential breakout scenarios. For example, use one cell to track the highest price in the last 15 minutes and another cell to see if the price is near that high, potentially signaling strength.

• Building Real-Time Alerts
Use Excel’s conditional formatting to highlight when the current price approaches or surpasses the highest price retrieved by RTI_HighestPrice_in_X_Mins. This helps you set up alerts or triggers without leaving Excel.

• Combining with Rolling Averages
Compare the highest price in the last few minutes with a short-term average (e.g., 5-minute SMA using RTI_SMA) to gauge momentum or identify overbought statuses at a very granular level.

Common Questions and Troubleshooting

1. "Why am I seeing 'No data seller is configured' as a result?"
   – You need to enable at least one data seller in your MarketXLS settings (e.g., Zerodha or AngelOne). Make sure they are active before using real-time functions.

2. "What if the symbol is invalid or not recognized?"
   – The function may return an error or possibly show unexpected data. Double-check the ticker is correct and recognized by your data seller.

3. "Why do I get 'ERR' or an error message?"
   – This could be due to an expired license, a temporary interruption in real-time data, or referencing a symbol that has not been subscribed to in the MarketXLS system.

4. "Can I use zero or negative minutes for minutesAgo?"
   – RTI_HighestPrice_in_X_Mins is intended for positive integer time frames. Passing zero or negative numbers will likely yield no meaningful data or cause an error.

By leveraging RTI_HighestPrice_in_X_Mins within Excel, you gain a powerful tool for intraday technical analysis, enabling you to stay on top of dynamic market movements and act on real-time price spikes—right in your spreadsheets.
