VRZ Detector — How I Built a Tool That Watches the Market So I Don't Have To

📊 TechtoGeek.com · Intraday Trading 📅 April 2026⏱ 5 min read

Meet VRZ Detector — my personal market alert system that pings me on Telegram the moment price approaches a key zone.

Nifty 50 30-min chart showing VRZ High and VRZ Low levels:

If you trade intraday like me,Myself and TradingView alone in my room :-), you know how mentally exhausting it gets — not the trades themselves, but the waiting. Staring at charts. Refreshing. Wondering if the level you marked at 7 AM still matters at 11 AM. That constant watch-duty drains you before the trade even shows up.

So I built something. I call it VRZ Detector. It’s not fancy, it’s not a recommendation engine, and it’s definitely not another indicator promising 95% accuracy. It’s a focused tool that does exactly one thing well — it watches the levels I care about, and tells me when price is getting close.

01 · CONCEPT What Even Is a VRZ?

VRZ stands for Visible Reversal Zone — or at least that’s my personal interpretation of what these levels represent. On a 30-minute chart, certain price points tend to act like invisible walls. Price hits them, stalls, and often reverses. I mark these zones manually at the start of every trading day.

🔴 VRZ-High

22,894 – 22,993

Strong overhead resistance zone. When price approaches here, the odds favour a rejection downward. Trade idea: Sell CE (Call Options).

🟢 VRZ-Low

22,183

Key demand / support area. When price dips to this zone, a bounce upward becomes the higher-probability move. Trade idea: Sell PE (Put Options).

The chart above from April 2 shows exactly this — the red dashed lines around 22,894 and 22,993 held as resistance, while the green dashed line at 22,183 marked a clear bottom before a sharp recovery. These aren’t random numbers; they come from structural highs and lows spotted on the 30-minute timeframe.

02 · THE PROBLEM Marking Levels Is Easy. Watching Them Is Not.

Here’s the real issue I ran into. Once I mark a VRZ on the 30-minute chart, I actually need to monitor it on the 5-minute timeframe. That’s where the trade setup forms. That’s where I actually pull the trigger.

But I can’t sit and watch a chart all day. I have other work to do, other screens to attend to. Missing a level by just a few minutes means missing the trade entirely. I needed something that would tap me on the shoulder and say — “hey, that level you marked? Price is right there.”

Enter VRZ Detector. The rule is simple: if the 5-minute candle closes within ±5 points of any marked VRZ-High or VRZ-Low, I get a Telegram notification. Instantly.

03 · THE PRODUCT A Simple Tool with a Focused Purpose

VRZ Detector Landing Page

In this tool we can add Indexes and also stocks Eg:TCS

The UI is intentionally minimal. You type in the instrument — could be Nifty 50, Nifty Bank, or any NSE stock — add it to the list, and hit Start. The tool fetches the master data, identifies swing highs and lows on the 30-minute chart, and begins monitoring on the 5-minute frame.

Once you hit start, the tool shows a live running status. It processes each instrument, extracts the significant highs and lows, and stores them for real-time comparison. No manual input of price levels required — the detection is automatic.

04 · WORKFLOW How It Works End-to-End

7:00 AM — Start the tool

Launch VRZ Detector. Type in your watchlist (e.g., Nifty 50, TCS, HDFCBank). Click Start.

Automatic level detection

The tool scans the 30-minute chart for structural highs and lows. These become your VRZ levels for the day.

Real-time monitoring begins

Every 5-minute candle close is compared against all stored VRZ levels. If price is within ±5 points — alert fires.

Telegram notification

You receive an instant alert: VRZ type (High/Low), exact level, and current price. You decide whether to trade.

You get on with your day

No chart watching needed. Only engage when the market comes to your level, not when you’re guessing.

05 · ALERTS The Telegram Bot in Act

Here’s what a real alert looks like. Clean, fast, actionable.

⚠️ VRZ HIGH HIT

Level: 22,894.00
Price: 22,891.5
Check TradingView!

⚠️ VRZ LOW HIT

Level: 22,183.20
Price: 22,187.0
Check TradingView!

No noise. Just the level, the price, and a prompt to act.

06 · SCALE-UP500 Stocks. Same Logic. Zero Extra Effort.

📁 CSV Batch Mode

Load all 500 Nifty stocks at once via a simple CSV file. No typing each one manually.

⏱ 7 AM Start → 9 AM Free

Start the tool at 7 AM before market open. By 9 AM, all levels are detected and monitoring is live.

This is the part I’m genuinely proud of. Marking VRZ levels manually across 500 stocks would take two hours of solid work every single morning. With the CSV batch feature, I start the tool at 7 AM, and by the time market opens at 9:15, every stock in the Nifty 500 is already being watched.

I only get a notification when something actually matters — when price is knocking on a key level for one of those 500 instruments. That’s the kind of coverage no human can replicate by manually watching charts.
