Vikram, a swing trader tracking 30 mid-cap stocks, would manually download a CSV of stock data every day. He would then calculate the Simple Moving Averages (SMAs) in Excel, but often forgot to check half of the stocks on his list.

After this workflow:

• At 3:30 PM, the market closes.
• By 3:32 PM, his Google Sheet is automatically updated with real-time stock data, including:

1. Symbol

2. Forecast

3. Confidence Level

4. Signal

For example, the system might show:

• LT.NS – Forecast: ↑ UP, Confidence: 82%, Signal: Golden Cross
• JSWSTEEL.NS – Forecast: ↓ DOWN, Confidence: 71%, Signal: High RSI

An email then arrives with key insights, like:

Top Pick: LT.NS → Strong buy setup

Avoid: JSWSTEEL → Overbought

Result: Higher win rate. Less screen time. More confidence.
