The Scenario
You've been swing-trading for two years. Your edge is trend confirmation — you enter positions early in a move and exit when momentum signals turn. You have 30 tickers in an Excel workbook and a column called "Trend Direction" that should tell you, for each ticker, whether the Aroon indicator and MACD crossover are aligned or conflicting.
The column has been blank for five days because every time you sit down to fill it, the process of making 60 API calls and manually interpreting the output for each ticker eats up the time you had budgeted for actual position sizing.
You have a watchlist. You don't have a signal column. Those are different things.
The bad version:
- Call Twelve Data's Aroon endpoint for the first ticker, extract Aroon Up and Aroon Down, apply the UPTREND/DOWNTREND/NEUTRAL logic, and write the label into column D.
- Call the MACD endpoint for the same ticker, check whether a crossover occurred in the last 3 periods, and write the crossover label into column E.
- Repeat 29 more times, and by ticker 20 you've spent more time entering signal labels than you would have spent just picking entries by feel.
The signal is only useful if it's current and complete. You have neither.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook. It reads the 30 tickers in column A and, through its built-in Twelve Data integration, fetches Aroon and MACD data for each and writes directional signal labels across the specified columns.
Fetch Aroon indicator values from Twelve Data for each stock in column A. Write Aroon Up into column B and Aroon Down into column C. In column D, write UPTREND if Aroon Up is above 70 and Aroon Down below 30, DOWNTREND if Aroon Down is above 70 and Aroon Up below 30, and NEUTRAL otherwise. Fetch MACD crossover status and write BULLISH CROSS or BEARISH CROSS into column E where a crossover occurred in the last 3 periods, otherwise FLAT.
What You Get
- Aroon Up and Aroon Down in columns B and C.
- Trend label in column D for each ticker.
- MACD crossover status in column E.
- Tickers with no Aroon data (insufficient history, unavailable symbol) noted in column F.
What If the Data Is Not Quite Ready
If you want Ichimoku Cloud instead of Aroon for trend direction
Fetch the latest Ichimoku Cloud values from Twelve Data for each ticker in column A. Write Tenkan-sen into column B and Kijun-sen into column C. In column D, write BULLISH if price is above the cloud, BEARISH if below, and NEUTRAL if inside. Fetch current price from Twelve Data and write into column E.
If you want Aroon values over the past 10 days to confirm a trend is holding
Fetch Aroon Up and Aroon Down from Twelve Data for each ticker in column A for the last 10 trading days. Write a time-series matrix with dates as row labels and tickers as column headers, filling Aroon Up values. Build a corresponding matrix for Aroon Down on an adjacent range so you can track trend signal stability over time.
If you want to compare the Aroon trend label with recent price direction
For each ticker in column A, fetch Aroon Up and Aroon Down from Twelve Data and write into columns B and C. Write the trend label into column D. Fetch the 5-day price return from Twelve Data and write into column E. In column F, write ALIGNED if the trend label and price direction agree, DIVERGING if they conflict.
Kill-chain: fetch Aroon and MACD, score each ticker, and sort the dashboard
Fetch Aroon Up, Aroon Down, and MACD crossover status from Twelve Data for each ticker in column A. Write into columns B, C, E. Write trend label into column D. Calculate a composite signal score: 2 for UPTREND with BULLISH CROSS, 1 for UPTREND with FLAT, 0 for NEUTRAL, -1 for DOWNTREND with FLAT, -2 for DOWNTREND with BEARISH CROSS. Write score into column F. Sort the workbook from highest to lowest score.
