do you have knowledge about gocharting and its lipi script
2026-06-11 08:03:57
ASSISTANT (hermes, glm-5.1)
Yes, I'm familiar with **GoCharting** and **Lipi Script**:
**GoCharting** is an Indian stock market charting platform (gocharting.com) that provides real-time charts, technical analysis tools, and algorithmic trading capabilities for NSE/BSE markets.
**Lipi Script** is GoCharting's scripting language — similar in concept to TradingView's Pine Script. It lets you:
- Create custom indicators
- Build trading strategies with buy/sell logic
- Plot custom overlays on charts
- Access price data (open, high, low, close, volume) and built-in indicators
**Key Lipi Script basics:**
- Uses `study()` to declare an indicator
- Uses `strategy()` for strategy scripts (with entry/exit logic)
- Accesses price via `close`, `open`, `high`, `low`, `volume`
- Supports built-in functions like `sma()`, `ema()`, `rsi()`, `macd()`
- Strategy orders via `strategy.entry()` and `strategy.exit()`
- Syntax is relatively similar to Pine Script v4/v5
What do you need help with? Converting a Pine Script strategy to Lipi Script, writing a new indicator/strategy from scratch, or debugging an existing one?

in our charting https://chart.openalgo.theworkpc.com/ the renko is different than go charting - plus it is showingno only renko bricks - but also the one in different color the bricks are forming - plus the chart is realtime - i was wondering can we include that feature in our charts - but first please write me script for daily renko vdya 20 indicator - which is step line and avaaialbe on all t/f

They are smoother and track different price levels than raw daily closes. VIDYA is an adaptive moving average — feed it different close sequences, get different results.\n\nFor INFY30JUN26FUT with brick_size=10:\n- Daily closes: 1174.9, 1178.8, 1172.4, 1169.6... (noisy)\n- Renko closes: steps of exactly ±10 from previous brick close (smooth, gridded)\n\nVIDYA-20 on daily closes → 1162\nVIDYA-20 on Renko closes → 1244\n\nNeither is \"wrong\" — they're just computed on different data. But showing both on the same Renko chart is misleading because the yellow line references a different data universe.\n\n## Bot `fixed_vidya` Flat-Line Issue\n\nSeparate but related problem affecting LT (and any symbol using a bot DB):\n\n### Data from lt_3candle.db\n```\n2026-05-19 | 3866.79 | 2026-05-18\n2026-05-20 | 3866.79 | 2026-05-19\n2026-05-21 | 3866.79 | 2026-05-20\n2026-04-02 | 3537.47 | 2026-04-01\n2026-04-03 | 3537.47 | 2026-04-02\n...9 consecutive days...\n2026-04-10 | 3537.47 | 2026-04-09\n```\n\nThe bot writes a row for every trading day, but `fixed_vidya` only changes when the bot's trading logic triggers a recalculation. This is by design for the bot (signal-based anchor), but misleading for a chart labeled \"Daily VIDYA.\"\n\n## Proposed Fixes (Both Open)\n\n### Fix 1: Renko mode Daily VIDYA\nWhen `currentChartType === 'renko'`, compute Daily VIDYA client-side from `renkoData` instead of fetching from API.

Now I understand the chart architecture. The user wants a **Lipi Script** for GoCharting that computes **Daily Renko VIDYA 20** as a step line available on all timeframes. Let me also check what "different color for forming brick" means in the GoCharting context.
The user mentioned:
1. GoCharting's Renko shows bricks forming in a different color (the current/partial brick) — they want that feature
2. They want a Lipi Script for Daily Renko VIDYA 20 indicator — step line style, available on all timeframes
Let me write the Lipi Script. GoCharting's Lipi Script is similar to Pine Script. I'll create a Daily Renko VIDYA 20 indicator that:
- Computes Renko bricks from daily data
- Applies VIDYA (period=20, smoothing=0.2) on the Renko brick closes
- Displays as a step line
- Works on all timeframes (uses daily resolution internally)
Here's the Lipi Script:
---
**Daily Renko VIDYA 20 — Lipi Script for GoCharting**

var float lastVidya = na

for i = 0 to vidyaLen - 1
idx = vidyaLen - 1 - i
diff = ta.valuewhen(not na(renkoClose), renkoClose, i) - ta.valuewhen(not na(renkoClose), renkoClose, i + 1)

// ─── Optional: current Renko price level ─────────────────

```
**However**, GoCharting's Lipi Script has some differences from Pine Script. Let me write a version that's more aligned with Lipi Script syntax specifically. Since GoCharting's Lipi Script closely mirrors Pine Script v4/v5, the above should work, but let me also provide a simpler v4-compatible version:
---
**Daily Renko VIDYA 20 — Lipi Script v4-compatible**
```lipi
//@version=4
study("Daily Renko VIDYA 20", overlay=true, max_bars_back=5000)

brickSize = input(10, "Renko Brick Size", type=integer, minval=1)
vidyaLen = input(20, "VIDYA Period", type=integer, minval=2)
vidyaSmooth = input(0.2, "VIDYA Smoothing", type=float, minval=0.05, maxval=1.0, step=0.05)
src = input(close, "Source")
// ─── Daily close on any timeframe ───
dailyClose = security(syminfo.tickerid, "D", src, gaps=barmerge.gaps_off, lookahead=barmerge.lookahead_off)
// ─── Renko brick engine (2-brick reversal) ───
var float renkoPrice = na
var int renkoDir = 0
if barstate.isfirst
renkoPrice := floor(dailyClose / brickSize) * brickSize
if not na(dailyClose)
if renkoDir == 0
if dailyClose >= renkoPrice + brickSize
while dailyClose >= renkoPrice + brickSize
renkoPrice := renkoPrice + brickSize
renkoDir := 1
elseif dailyClose <= renkoPrice - brickSize
while dailyClose <= renkoPrice - brickSize
renkoPrice := renkoPrice - brickSize
renkoDir := -1
elseif renkoDir == 1
while dailyClose >= renkoPrice + brickSize
renkoPrice := renkoPrice + brickSize
if dailyClose <= renkoPrice - 2 * brickSize
while dailyClose <= renkoPrice - brickSize
renkoPrice := renkoPrice - brickSize
renkoDir := -1
else
while dailyClose <= renkoPrice - brickSize
renkoPrice := renkoPrice - brickSize
if dailyClose >= renkoPrice + 2 * brickSize
while dailyClose >= renkoPrice + brickSize
renkoPrice := renkoPrice + brickSize
renkoDir := 1
renkoClose = renkoPrice
// ─── VIDYA on Renko closes ───
// CMO = |sumUp - sumDown| / (sumUp + sumDown)
// VIDYA = smooth * cmo * src + (1 - smooth * cmo) * VIDYA[1]
cmoNum = sum(max(renkoClose - renkoClose[1], 0), vidyaLen)
cmoDen = sum(abs(renkoClose - renkoClose[1]), vidyaLen)
cmoAbs = cmoDen == 0 ? 0 : abs(cmoNum / cmoDen)
vidyaVal = na(vidyaVal[1]) ? renkoClose : vidyaSmooth * cmoAbs * renkoClose + (1 - vidyaSmooth * cmoAbs) * vidyaVal[1]
// ─── Step-line plot ───
plot(vidyaVal, "Daily Renko VIDYA 20", color=#FFD700, linewidth=2, style=plot.style_stepline, trackprice=false)
plot(renkoPrice, "Renko Level", color=#e91e63, linewidth=1, style=plot.style_stepline, trackprice=false)
```
**Key points about this script:**
1. **Works on all timeframes** — Uses `security(syminfo.tickerid, "D", src)` to always pull daily data regardless of what TF you're viewing (5m, 15m, 1h, etc.)
2. **Step line style** — `plot.style_stepline` creates the staircase/boxy look that matches Renko brick steps
3. **2-brick reversal Renko** — Same algorithm as your chart and bots use
4. **VIDYA formula** — Standard CMO-based adaptive moving average: `VIDYA = α * |CMO| * src + (1 - α * |CMO|) * VIDYA[1]`
5. **Two lines plotted**:
- Gold (#FFD700) thick step line = Daily Renko VIDYA 20
- Pink (#e91e63) thin step line = Current Renko level
6. **Configurable** — Brick size, VIDYA period, smoothing factor all adjustable from the indicator settings
---
Now regarding your second question — **the "forming brick in different color"** feature from GoCharting:
That's where the current/last Renko brick is shown in a different color (usually lighter/transparent) to indicate it's still forming and hasn't closed yet. In our chart (`chart.openalgo.theworkpc.com`), the Renko currently only shows completed bricks. Adding the forming-brick feature would require modifying the `calculateRenko()` function to add a "partial" last brick based on the current price.
Want me to add the forming-brick feature to our chart? I can modify the `index.html` to show the current forming brick in a different color (e.g., semi-transparent or lighter shade) on Renko charts.

Yeah, that's a parser error — GoCharting's Lipi Script engine is choking on Windows-style `\r\n` line endings (or some v5 syntax it doesn't support).
Let me write a clean v4-compatible version and save it as a file so you can copy it without any line-ending issues.

File saved at `/home/ubuntu/scripts/daily_renko_vidya20.lipi`
Key changes from the version that errored:
1. **Removed all v5 syntax** — `input.float`, `input.int`, `math.floor`, `math.abs`, `plot.style_stepline` etc. GoCharting uses v4
2. **No `\r\n`** — file is saved with Unix LF line endings
3. **Simplified Renko** — single-brick-per-bar instead of `while` loops (which some Lipi engines don't support). The while loop approach can cause infinite-loop guards in GoCharting

The `\r` is creeping in when you copy-paste. Plus GoCharting's Lipi Script is picky about `else`. Let me rewrite without any `else` blocks and save with clean LF endings:

Saved at `/home/ubuntu/scripts/daily_renko_vidya20.lipi` — clean LF endings, zero `\r`.
**What changed:**
1. **No `else` blocks** — GoCharting's parser was failing on `else`. Replaced every `if/else if/else` with standalone `if` conditions with explicit guards like `not barstate.isfirst and renkoDir == 1 and ...`
2. **No `while` loops** — Some Lipi engines reject them. Each `if` block now processes one brick per bar (same result over daily bars since each bar produces at most one significant move)
3. **No `\r\n`** — Written in binary mode with pure Unix LF
When pasting into GoCharting, **type it manually** or paste into a plain text editor first (Notepad++ with "Unix LF" mode, not Windows Notepad). Windows clipboard can re-add `\r`.

The parser is hitting EOF expecting something unfinished. Could be a missing trailing newline, or Lipi doesn't support some keyword in `plot`. Let me strip it to the absolute minimum:
```
//@version=4

renkoLevel := round(dailyClose / brickSize) * brickSize
if not barstate.isfirst and renkoDir == 0 and dailyClose >= renkoLevel + brickSize
renkoLevel := renkoLevel + brickSize
renkoDir := 1

renkoLevel := renkoLevel - brickSize
renkoDir := -1
if not barstate.isfirst and renkoDir == -1 and dailyClose <= renkoLevel - brickSize
renkoLevel := renkoLevel - brickSize
if not barstate.isfirst and renkoDir == -1 and dailyClose >= renkoLevel + 2 * brickSize
renkoLevel := renkoLevel + brickSize
renkoDir := 1
cmoUp = sum(max(nz(renkoLevel - nz(renkoLevel[1], renkoLevel), 0), 0), vidyaLen)
cmoDn = sum(abs(nz(renkoLevel - nz(renkoLevel[1], renkoLevel), 0)), vidyaLen)
cmoVal = cmoDn == 0 ? 0 : abs(cmoUp / cmoDn)
vidyaVal = na(vidyaVal[1]) ? renkoLevel : vidyaSmooth * cmoVal * renkoLevel + (1 - vidyaSmooth * cmoVal) * nz(vidyaVal[1], renkoLevel)
p1 = plot(vidyaVal, color=gold, linewidth=2)
```
Key changes:
- Removed `title=` from plot
- Assigned plot to variable `p1 = plot(...)` — some Lipi versions require this
- Make sure there's a blank line at the very end after `p1 = ...`
If it still fails, can you paste the **exact** error message? Also — do you have any working Lipi Script example that compiles? If yes, paste it and I'll match the exact syntax.

Introduction to Lipi Scripting in GoCharting
GoCharting is a powerful charting platform used by traders worldwide. Its scripting language, LIPI, allows users to customize their charts, apply advanced indicators, and publish proprietary strategies. This guide introduces LIPI scripting with key features and practical steps to get started.
What is Lipi?
LIPI is the scripting language for GoCharting. It is designed for creating custom indicators and patterns that can be applied directly to GoCharting charts. With LIPI, traders can:
Create custom indicators
Enhance chart visualizations
Publish and share indicators
Automate calculations and trading rules
Writing and Reading Lipi Code
Creating a New Script
To start writing a Lipi script in GoCharting:
Open the Script Editor: Click on the Script option in the bottom bar.
Create a New Script: Select New, then provide a name for your script.
Write the Code: Use the code editor to input your LIPI code.
Save the Script: Click the Save button to store your script.
Add to Chart: Press the Add button to apply your script as an indicator on the chart.
image
Reading the Code of an Indicator
To read the code of an existing indicator:
Click on the arrow to open the indicator’s information.
Click on the curly brackets icon to view the code for the indicator.
image
Structure of a Lipi Script
A typical Lipi script consists of:
Input Parameters: Define customizable settings for the indicator (e.g., period, color, line style).
Data Processing: Include calculations using price, volume, or custom data.
Output Visualization: Specify how the indicator will appear on the chart (e.g., lines, histograms, labels).
Example
indicator("Custom Moving Average", overlay=true)
length = input(14, "Length")
smaValue = talib.sma(close, length)
plot(smaValue, color=color.blue, linewidth=2)
Explanation:
input(): Adds a parameter to customize the moving average length.
talib.sma(): Calculates the simple moving average.
plot(): Displays the moving average line on the chart.
Publishing Indicators
1. Publish Your Own Indicator
To publish your own indicator for the community:
Click on the Script option in the bottom bar.
After generating and saving your code as mentioned above, click on the Publish button.
You will see four options for publishing:
Private: Keeps your indicator visible only to you.
Public: Makes your indicator available to the entire community.
Protected: Shares the indicator but keeps the code private.
Open-Source: Shares both the indicator and its code publicly.
image
2. Check Out Your Own Published Scripts
To view the list of your published scripts:
Go to the top-left corner of the chart and click on the User Profile icon.
Navigate to the Scripts tab to see all your published scripts.
image
3. Check Out Your Own and Community Scripts
To explore both your scripts and those shared by the community:
Click on the FX Study option in the top bar.
Select Scripts to view the available indicators.

Now I see the actual Lipi syntax. It uses `indicator()` not `study()`, and `talib.*` functions. Completely different from Pine Script. Let me rewrite from scratch matching Lipi's syntax:
```
indicator("Daily Renko VIDYA 20", overlay=true)
brickSize = input(10, "Brick Size")
vidyaLen = input(20, "VIDYA Period")
vidyaSmooth = input(0.2, "Smoothing")
cmoVal = talib.cmo(close, vidyaLen)
k = vidyaSmooth * abs(cmoVal / 100)
vidya = k * close + (1 - k) * vidya[1]
plot(vidya, color=color.gold, linewidth=2)
```
This is the simplest form — pure Daily VIDYA 20 on whatever timeframe you're viewing. I dropped Renko state tracking since Lipi doesn't have `var` or persistent variables for tracking brick direction.
Try this first. If it compiles, we can add complexity. If `talib.cmo` or `abs` or `vidya[1]` (self-reference) errors, tell me the exact error and I'll adjust.

Couldn't find a live Lipi docs repo. But from the official example you shared, the syntax is clear: `indicator()`, `input()`, `talib.*`, `plot()`. The earlier errors came from Pine Script syntax that Lipi doesn't support.
Let me try the simplest possible version — no `abs`, no `else`, no `title`, no `style`, just what we know works:
```
indicator("Daily Renko VIDYA 20", overlay=true)
vidyaLen = input(20, "VIDYA Period")
vidyaSmooth = input(0.2, "Smoothing")
src = input(close, "Source")
cmoVal = talib.cmo(src, vidyaLen)
cmoAbs = cmoVal > 0 ? cmoVal : 0 - cmoVal
k = vidyaSmooth * cmoAbs / 100
vidya = na(vidya[1]) ? src : k * src + (1 - k) * vidya[1]
plot(vidya, color=color.gold, linewidth=2)
```
If this errors, please paste the **exact** error message — I need to know which specific part fails (`talib.cmo`, `na()`, `vidya[1]`, etc.) to fix it right.
