walls.read()Put walls & call walls
Where option writers defend, why price stalls there, and how to mark both before 9:15.
90 minutes, live on real Nifty charts. The rules institutions trade by, rebuilt for retail: walls, the 5-layer setup, and sizing that compounds slowly and consistently.
Press play for a preview of exactly what happens in the webinar, minute by minute.

I'm K. Gowtham Reddy. My passion for markets turned into code: I've written trading logic for hedge funds across US and Indian markets. Institutions don't guess. Their algorithms trade around walls, liquidity and volatility with fixed rules and fixed risk.
Most retail traders lose because they fight that machine with tips, impulse and oversized bets. The Codex is how I solved that: the same rule-based discipline, rebuilt as our own technology for the retail trader.
“The market already runs on code. I just taught retail traders to speak it.”— K. Gowtham Reddy · we code.
Press play. The same candles reach both traders. One reacts with emotion, one runs the Codex step by step.
An illustrative scenario for education, not a real track record or a promise of returns. Losing days happen with any method; the Codex limits how much one day can cost.
A replay of how the 5 layers read price between the put wall and the call wall. Watch how many candles it skips before one setup qualifies.
No tips, no "jackpot" trades. A rules-based way to read the market and size every position so one bad day can't undo a good month.

setup.check(5)Trend, wall, candle, momentum and volume. Four of five or no trade, on live Nifty charts.
size(risk, stop)Lots = risk budget ÷ stop × lot size. Book half at 1R, trail the rest. The same every time.
size_up_when(…)The rule that turns small, steady wins into compounding. Shown only to people in the room.
Each 100 trades is a block. The lift only goes up a risk tier when the block passes the gate. Press run and watch: the first crore is the slowest, and every floor after comes faster.
Change the sliders above and the code updates. Run it in any Python notebook to test your own edge, no account needed.
After 100 trades: average ≥ +0.20R and dip under 8% → next tier, a little more risk.
Positive but below the gate, or a dip of 8–12% → stay on the same tier for another 100.
Negative block, or a dip of 12%+ → one tier down. Safety beats speed.
# The Crore Elevator · per trade edge E = W × RR − (1 − W) − costs # must be > 0 or the lift never moves risk r = tier_band(block) # I 0.1–0.5% · II 0.2–0.6% · … · VI 0.6–1.0% (cap) win capital ×= 1 + r × RR loss capital ×= 1 − r every 100 trades → gate(avg_R, max_dip) → up · hold · down
Look at the last candle. Decide like a Codex trader: take it or skip it. Then see the 5-layer check and the rule behind it.
Every chart is a real pattern type from the Codex lessons, drawn for education.

Educational practice charts, not live market data and not trade calls.
The Codex translates one into the other. Pick a habit you know too well and watch it become a rule your chart can't ignore.
Both courses teach you to turn how you read the market into Pine Script on TradingView: your rules, visible and testable. Start with the free webinar; choose your depth after.
Write your trading rules as code, with the Codex as your template.

Education only: no tips, no trade calls and no promise of returns. You can join only after attending the free webinar or a call with our team.
Browse the course like a code repository: what you learn, the Pine Script you'll write, and what you ship each week.
Every week runs the same loop, so consistency becomes a habit before it's a rule.
The week's idea on live Nifty charts, then the rule written out together.
[8:00 PM · 90 min]You write the Pine Script. Templates and hints ready when you're stuck.
[8:00 PM · 60 min]Your script on screen. What it gets right, what it misses, and why.
[8:00 PM · 60 min]The week's walls and setups replayed, so you can see your rules in action.
[Recorded · 30 min]Answer honestly. The finder tells you where to start. You can always go deeper later.
We'll match you to Code Your Code or Code Depth, with the reason.
Move the slider. The Codex writes the first six lines with your numbers. Line 7 is written with you, live.
A short daily newsletter on WhatsApp: how to read walls, one candle pattern explained with the 5 layers, and a recap of how markets behaved vs how retail traders reacted. Two minutes a day to build the habit.
Education only. No buy/sell calls, no tips, no paid groups. Lessons use archived charts.
Yes. No card, no payment. At the end we explain our programs for anyone who wants to go deeper. Joining one is optional.
Yes. We start from how an option chain works and build up to walls, the 5-layer setup and sizing. Bring a notebook.
No. This is education: how to read the market and manage risk with clear rules. Every decision stays yours.
After you register, tap "Confirm on WhatsApp". The Zoom link and reminders (1 day and 1 hour before) come on that chat and by email.
Code Your Code if you want to read walls and build your own indicator. Code Depth if you also want a backtested system, risk tiers and 1:1 reviews. Fees and full details are on the courses page, and we help you choose after the webinar.
No. We teach Pine Script from zero, using the Codex rules as templates. If you can write down how you trade, you can code it.
Registered traders get a replay for a limited time. Line 7 is covered live, with Q&A, so it's best to attend.
Learn the rules that keep you in the game, then compound slowly. Saturday · 7:00 PM IST.
