Covers data sourcing, backtest methodology, intraday whipsaw computation, and common pitfalls.\ntrigger: daily renko chart, VIDYA on daily, daily anchor, line in stone, renko vidya analysis, intraday whipsaw, ±0.5% skip zone\n---\n\n# Daily Renko + VIDYA Analysis Methodology\n\nAnalysis of daily Renko(2) charts with VIDYA-20 and SMA-2, using the \"Line in Stone\" approach for intraday signal validation.\n\n## Core Rules\n\n1. **DATA SOURCE**: Always use the **chart DB** (`/var/www/openalgo-chart/api/dbs/<symbol>_5min.db`) — this is NSE spot data, the same data `chart.openalgo.theworkpc.com` serves. Do NOT use the Morning Sniper DB (`/home/ubuntu/bots/morning_sniper/dbs/`) — that's NFO futures data with different prices. **The Daily VIDYA anchor must also read from the 5-min DB** (not daily aggregates from the chart API). Daily aggregates lose intraday reversals, producing different renko bricks (857 daily bricks vs 2714 5-min bricks for SBIN). The anchor now reads 5-min closes directly and builds renko with `Math.floor` start, matching the chart and bot exactly.\n\n2. **VIDYA IS LINE IN STONE**: Yesterday's VIDYA-20 value = today's FIXED horizontal anchor. It does NOT move during the trading day. When computing intraday whipsaws, VIDYA stays at yesterday's close-of-day value. The user WILL correct you if you show VIDYA as a rolling value.\n\n3. **SMA-2 is rolling**: SMA-2 on Renko bricks updates with each new 5-min brick. It crosses the fixed VIDYA line — that's the signal.\n\n4. **±0.5% Skip Zone**: If price is within ±0.5% of VIDYA anchor → HOLD existing position, DO NOT flip. This is the \"smoky day\" zone where SMA2 dances around VIDYA and whipsaws destroy profits.\n\n5. **15-pt Clearance Rule**: On intraday 5-min chart, only take entry when SMA2 is 15+ pts clear of VIDYA. This confirms direction on clear days and prevents premature entry on smoky days. Must be COMBINED with the ±0.5% zone rule.\n\n6. **Combined Rule for Carried Positions**:\n - Price > VIDYA + 0.5% AND SMA2 15+ pts above VIDYA → **GO LONG**\n - Price < VIDYA - 0.5% AND SMA2 15+ pts below VIDYA → **GO SHORT**\n - Price within VIDYA ± 0.5% → **HOLD existing position, no new entries, no flips**\n - On smoky days (price hugging VIDYA): **BOOK PROFIT, go flat, re-enter when direction is clear**\n\n7. **This is for OVERNIGHT positions, not intraday day-trading.** The user carries positions overnight. The analysis determines whether to hold, book out, or enter. Do NOT treat this as day-trading signals.\n\n## Backtest Results (INDIGO, Ja

So `nice_round(latest_close*0.01)` = `nice_round(−3011)` = **0.01**\n → 1-paisa Renko bricks on a ₹3-lakh series.\n2. `build_renko_bricks()` allocates EVERY brick in a Vec with no cap.

Reference: references/finratio-fork.md (fork overview),\nreferences/15m-interval-overlay.md (the tcharts 15m LIPI/RSI pattern this copies).\n\n## Part A — 3-Candle data verified EXACT (\"very off\" was NOT a data bug)\n\nAudit sequence — recompute independently BEFORE touching any code:\n\n1. Replicate the server exactly in Python from the raw 5-min DBs\n (`/var/www/openalgo-chart/api/dbs/<sym>_5min.db`, READ-ONLY):\n - pair 5m candles: for common timestamps, values = A_leg×lotA − B_leg×lotB per\n OHLC element (spread) or sum (sum mode); skip rows where any element is 0.0;\n high = max(four combined values), low = min(four combined values) — note the\n spread daily HIGH is max of combined OHLC spreads, NOT spread(maxA, minB).\n - daily OHLC: open = first 5m open, high = max, low = min, close = last 5m close.\n - 3-Candle for day D = 0.20·mean(D−2) + 0.40·mean(D−1) + 0.40·mean(D),\n mean = (O+H+L+C)/4. Newest day gets 40% together with D−1; D−2 gets 20%.\n This matches app.py `compute_3candle_from_5min` (the chart of record) 1:1 and\n Rust `compute_3candle_from_5min` (finratio main.rs ~line 746) 1:1. Verified\n against app.py source directly Aug 31.\n2. Diff against `/api/daily-values/<A-B>?mult=1&mode=<mode>` (raw values, mult=1).\n3.

Verifier script\n kept at skill dir `scripts/check_all_pairs.py`.\n\n### Why it LOOKS off — explain to the user, do NOT \"fix\"\n1. TODAY's 3-Candle is computed off the still-forming daily candle → it moves with\n every 5-min candle all day and only settles at close. Two reads an hour apart\n legitimately differ.\n2. 60% of the weight sits on D−1 and D−2 → after a sharp trend day the line lags\n price BY DESIGN. HAL-DLF 08-26 example: day mean ≈8.2M while 3-Candle read\n ≈9.0M because 80% of the weight is the two older, higher days.\n3.

I read the mechanics of both pages from the code. Here's the strategy, in plain trader terms.
## What the two pages actually tell you
1. /ratio/ (A/B) = WHO is stronger. It's a RELATIVE signal only. Ratio rising = A stronger than B; falling = B stronger than A. It says nothing about whether the market is going up or down.
2. /finratio/ SUM (A+B) = WHICH WAY the whole complex is moving. It's the ABSOLUTE signal. SUM rising = both legs going up (market up); falling = both down.
## Your 6k loss was the trap
You shorted because price was under SMA20 (a sell signal). But the SUM was rising — the whole market was going up. So your leg, even though it was the "weak" one relative to the other, still went UP in absolute terms. Your short lost.
The ratio told you "A is weak RELATIVE to B" — it never told you "A will fall in absolute terms." You applied a relative signal to a single-leg trade, and the absolute move (SUM) killed you.
## The strategy — two ways to use both together
**Option 1 — Go market-neutral (the ratio page's real purpose).** Trade BOTH legs: short A / long B when the ratio is under SMA20, long A / short B when over. Because you're long one and short the other, the SUM cancels out — you only make or lose on the RELATIVE move. This is immune to the 6k loss. The SUM becomes irrelevant.
**Option 2 — Single-leg, but gate it with the SUM.** Only take a directional trade when the ratio AND the SUM agree on absolute direction:
- Ratio rising (A stronger) AND SUM rising (market up) → LONG A (strongest leg in an up market).
- Ratio falling (B stronger) AND SUM falling (market down) → SHORT B (weakest leg in a down market).
- They disagree (ratio up but SUM down, or ratio down but SUM up) → go flat, or do the hedged pair trade instead.
Your 6k loss was exactly the "disagree" case: ratio said short, SUM said up. Under Option 2 you'd have skipped it.
## The one-line rule
The ratio picks WHICH leg; the SUM decides WHETHER the market is with you. Never trade a single leg off the ratio alone — that's the trap that cost you 6k.
Want me to backtest Option 2 on a specific pair (tell me which two stocks) to see how often the ratio and SUM agree, and whether the gated single-leg version beats the raw ratio signal? I can pull the real 5-min data from your own DBs.

Backtest done on real data (HPCL = HINDPETRO, db `hpcl`, Jan 1–Sep 2, 146 trading days, daily-close swing, enter next day, exit on flip).
## The plain-language version
Your 6k loss: you shorted HPCL because it was under SMA20. But the SUM (HPCL + INDUSINDBK) was rising — the whole market was going up. So HPCL went up anyway and your short lost. The ratio/SMA20 told you HPCL was weak *relative to the other stock*, not that it would fall in absolute terms.
The fix idea: only short when the SUM is also falling (market down), only buy when the SUM is also rising (market up). If they disagree, stay flat.
## What the backtest actually says
| Rule | Trades | Win% | Net pts | Net Rs (HPCL lot 2025) |
|------|--------|------|---------|------------------------|
| BASE: HPCL vs SMA20 alone (what you did) | 21 | 19% | **-59.4** | **-120,386** |
| GATED: only when SUM agrees | 13 | 31% | **-25.2** | **-51,131** |
The gate works — it cuts the loss by more than half and raises win rate from 19% to 31%. The trap days (base and SUM disagree) are 14% of days, and those are exactly the days that were killing you.
## But the honest verdict
The gate helps, but **both versions still lose money**. The base signal itself (HPCL vs SMA20) is a bad signal on this stock — 19% win rate even ungated. Gating a bad signal makes it lose less, not win.
So the real answer to "is there a strategy": the SUM gate is a genuine improvement and worth keeping, but on HPCL you'd still be net negative. The gate is a *filter that avoids the worst days* — it is not a *profit engine* by itself.
Two things I can do next:
1. Test the gate on a pair where the base signal is actually good (e.g. INDUSINDBK vs its SMA20, gated by the same SUM) — the gate might turn a winning base into a better one.
2. Test the market-neutral version (short HPCL / long INDUSINDBK when ratio falls) — that's the ratio page's real purpose and is immune to the SUM direction entirely.
Which do you want? Or tell me the exact trade you took (date, side, which stock) and I'll replay that specific day to show you precisely where the SUM was pointing.

so lets do onething - hpcl/indusind as pair - look at sum - if sum is above sma 20 - then both long else short | 2. hpcl remain buy if sum is above sma20 | and sell indusind bank if sum is below sma20

Let me build both rules exactly as you stated them, on the real data.
