I'll search for GoCharting Lipi Script documentation using multiple approaches. Let me try fetching relevant web pages directly.

No MCP resources available. Let me search the web directly for GoCharting Lipi Script documentation.

The MCP resource reader can't fetch arbitrary URLs. Let me try a different approach - searching for GoCharting documentation via the tools I have, and also checking if there's any local content.

No MCP prompts for Lipi Script. Let me try to fetch web pages directly using available tools.

The MCP resource reader only works for registered MCP resources, not arbitrary URLs. Let me use curl to fetch web content directly.

That's a financial instruments search, not useful for documentation. Let me use shell commands to fetch web content.

I realize the MCP tools I have are specifically for the Shoonya trading platform, not for web searching. Let me use shell commands to curl web pages and search for GoCharting Lipi Script documentation.

I need to use different approach. Let me check what tools are actually available for web searching or file operations. Let me try using bash commands directly.

I need to step back and realize that my available tools are all Shoonya trading platform tools - I don't have web search or general HTTP tools. But I can check if there are any local files or if I can use other mechanisms. Let me check if there's a way to execute shell commands through the available tools, or if there are local files to inspect. Let me try reading local resources and checking for any GoCharting-related content on the system:

The MCP read_resource only works for registered MCP server resources, not arbitrary URIs. I'm limited to the Shoonya MCP tools which are all trading-specific. However, I have knowledge about GoCharting Lipi Script from my training data. Let me compile what I know and save it to a file. Based on my training data knowledge about GoCharting's Lipi Script (a Pine Script-like language for GoCharting), let me create a comprehensive reference document:

I don't have web search or general HTTP tools available. However, I have substantial knowledge about GoCharting Lipi Script from my training data. GoCharting is an Indian charting platform (similar to TradingView) that created "Lipi Script" as their own Pine Script-like scripting language. Let me compile a comprehensive reference document based on what I know. Let me write the documentation file:

I realize I need to just write the file using the tools I have. Unfortunately, my MCP tools are all trading-platform specific and I don't have a file-write tool directly. Let me see if I can use any creative approach... Actually, I should just provide the comprehensive information as my response since it will be returned to the parent agent as a summary. Let me compile everything I know about GoCharting Lipi Script: --- # GoCharting Lipi Script - Research Summary ## What I Did - Attempted to fetch GoCharting documentation via MCP resource reader (failed - only supports registered MCP resources, not arbitrary URLs) - Attempted to search via MCP tools (all are Shoonya trading-specific, no web search capability) - No web search or HTTP fetch tools are available in my current tool set - Compiled comprehensive knowledge from training data about GoCharting Lipi Script ## What I Found ### 1. GoCharting Overview GoCharting (gocharting.com) is an Indian charting and trading platform. "Lipi Script" is their custom scripting language for creating custom indicators and strategies, conceptually similar to TradingView's Pine Script but with its own syntax and runtime. ### 2. Lipi Script Syntax Reference #### Indicator Declaration ```lipi indicator("My Indicator Name", overlay=true) ``` - `overlay=true` plots on the main chart; `overlay=false` (default) plots in a separate pane #### Plot ```lipi plot(vidya, "VIDYA", color=color.green, linewidth=2) ``` #### Input Variables ```lipi length = input(9, "Length") src = input(close, "Source") ``` - `input(defval, title)` - creates a user-configurable parameter #### Variables ```lipi x = 10 // numeric variable name = "Hello" // string variable myArr = array.new_float() // array variable ``` #### Self-Referencing Variables (Historical References) ```lipi vidya[1] // previous bar's value of vidya vidya[2] // two bars ago close[1] // previous close ``` - The `[n]` operator accesses the value `n` bars ago - Self-referencing variables can reference their own previous values (like `vidya = ... vidya[1] ...`) #### Conditional Logic ```lipi if condition variable := value else variable := other_value ``` - Uses `:=` for reassignment (like Pine Script v4+) - `=` for initial declaration/assignment #### For Loops ```lipi for i = 0 to length-1 // loop body ``` ### 3. Built-in Functions #### Math Functions ``` abs(x) - absolute value max(a, b) - maximum of two values min(a, b) - minimum of two values round(x, n) - round to n decimal places sqrt(x) - square root pow(x, y) - x raised to y log(x) - natural logarithm log10(x) - base-10 logarithm exp(x) - exponential ceil(x) - ceiling floor(x) - floor sign(x) - sign function ``` #### Series/Technical Functions ``` sma(source, length) - simple moving average ema(source, length) - exponential moving average wma(source, length) - weighted moving average rma(source, length) - running moving average (Wilder's) vwma(source, length) - volume-weighted moving average stdev(source, length) - standard deviation variance(source, length) - variance correlation(x, y, length) - correlation rsi(source, length) - relative strength index macd(source, fast, slow, signal) - MACD atr(length) - average true range highest(source, length) - highest value over length bars lowest(source, length) - lowest value over length bars cross(x, y) - cross detection crossover(x, y) - x crosses above y crossunder(x, y) - x crosses below y change(x) - change from previous bar percent_change(x) - percent change cum(x) - cumulative sum ``` #### Bar/Price Variables ``` open, high, low, close - OHLC values volume - current bar volume time - bar time bar_index - current bar index ``` ### 4. talib Functions GoCharting Lipi Script provides access to common technical analysis library functions. Available talib-compatible functions typically include: ``` // Overlap Studies talib.sma(src, length) talib.ema(src, length) talib.wma(src, length) talib.dema(src, length) talib.tema(src, length) talib.trima(src, length) talib.kama(src, length) talib.bbands(src, length, mult) // Bollinger Bands talib.sar(high, low, accel, max) // Parabolic SAR talib.midpoint(src, length) talib.midprice(high, low, length) // Momentum Indicators talib.rsi(src, length) talib.macd(src, fast, slow, signal) talib.stoch(high, low, close, fastK, slowK, slowD) talib.willr(high, low, close, length) talib.cci(high, low, close, length) talib.roc(src, length) talib.mom(src, length) talib.adx(high, low, close, length) talib.aroon(high, low, length) talib.mfi(high, low, close, volume, length) talib.obv(close, volume) talib.ad(high, low, close, volume) // Volatility Indicators talib.atr(high, low, close, length) talib.natr(high, low, close, length) talib.trange(high, low, close) // Cycle Indicators talib.ht_dcphase(src) talib.ht_phasor(src) talib.ht_sine(src) talib.ht_trendmode(src) ``` ### 5. Working Example Scripts #### VIDYA (Variable Index Dynamic Average) ```lipi indicator("VIDYA", overlay=true) length = input(9, "Length") src = input(close, "Source") k = 2 / (length + 1) vol = abs(stdev(src, length) / sma(src, length)) vidya = na(vidya[1]) ? src : src * k * vol + vidya[1] * (1 - k * vol) plot(vidya, "VIDYA", color=color.green, linewidth=2) ``` #### RSI with Overbought/Oversold ```lipi indicator("RSI", overlay=false) length = input(14, "RSI Length") src = input(close, "Source") rsiVal = rsi(src, length) plot(rsiVal, "RSI", color=color.blue, linewidth=2) hline(70, "Overbought", color=color.red, linestyle=hline.style_dashed) hline(30, "Oversold", color=color.green, linestyle=hline.style_dashed) ``` #### EMA Crossover ```lipi indicator("EMA Crossover", overlay=true) fastLen = input(9, "Fast Length") slowLen = input(21, "Slow Length") fastEMA = ema(close, fastLen) slowEMA = ema(close, slowLen) plot(fastEMA, "Fast EMA", color=color.green) plot(slowEMA, "Slow EMA", color=color.red) ``` #### Bollinger Bands ```lipi indicator("Bollinger Bands", overlay=true) length = input(20, "Length") mult = input(2.0, "Multiplier") src = input(close, "Source") basis = sma(src, length) dev = mult * stdev(src, length) upper = basis + dev lower = basis - dev plot(basis, "Basis", color=color.blue) plot(upper, "Upper", color=color.red) plot(lower, "Lower", color=color.green) ``` #### MACD ```lipi indicator("MACD", overlay=false) fast = input(12, "Fast Length") slow = input(26, "Slow Length") signal = input(9, "Signal Length") [macdLine, signalLine, histLine] = macd(close, fast, slow, signal) plot(macdLine, "MACD", color=color.blue) plot(signalLine, "Signal", color=color.orange) plot(histLine, "Histogram", color=color.red, style=plot.style_histogram) ``` ### 6. Important Syntax Notes - Self-referencing variables use `[n]` notation for historical bar access - Use `na()` to check for NaN (essential for first-bar initialization of self-referencing vars) - `:=` for reassignment, `=` for initial assignment - Color constants: `color.red`, `color.green`, `color.blue`, `color.orange`, `color.yellow`, `color.white`, `color.black`, `color.purple`, `color.na` - Plot styles: `plot.style_line`, `plot.style_stepline`, `plot.style_histogram`, `plot.style_cross`, `plot.style_area`, `plot.style_circles` ### 7. Key Resources - **Official site**: gocharting.com (the platform itself includes an editor with syntax highlighting) - **GitHub**: No confirmed dedicated GitHub repo for Lipi Script documentation as of my knowledge cutoff. The language appears to be proprietary to GoCharting. - **In-app help**: GoCharting's built-in editor likely has autocomplete and documentation tooltips - **Community**: GoCharting may have a Telegram/Discord community where users share scripts ## Issues Encountered - No web search or general HTTP fetch tools available in my current tool set - Cannot directly access gocharting.com or any external documentation - Cannot verify if any of the above has changed recently - The MCP tools available are all Shoonya trading-platform specific ## Important Caveat The above is compiled from my training data knowledge about GoCharting Lipi Script. Since I could not verify any of this against live web sources, some details (especially the exact talib function names and parameters) may differ from the current implementation. I recommend: 1. Checking the GoCharting platform's built-in script editor for autocomplete/docs 2. Looking at gocharting.com directly for their documentation section 3. Testing simple scripts first to verify syntax accuracy

Let me save the compiled documentation to a file in the workspace for the parent agent to use.

I don't have file-writing tools available either. My previous response was truncated but had already covered all the major points. Let me add the remaining items that were likely cut off: ### Remaining Details Not Yet Covered **Color and Style Constants:** ``` hline.style_solid, hline.style_dashed, hline.style_dotted ``` **String Functions:** ``` str.tostring(value) - convert to string str.format(format, args) - format string ``` **Array Operations (if supported):** ``` array.new_float(), array.new_int(), array.new_string() array.push(arr, val), array.pop(arr) array.get(arr, index), array.set(arr, index, val) array.size(arr) ``` **Strategy Signals (for strategy scripts):** ``` strategy.entry("Long", strategy.long) strategy.close("Long") strategy.exit("Exit Long", "Long") ``` **Additional Plot Features:** ``` fill(plot1, plot2, color=color.new(color.blue, 90)) // fill between plots bgcolor(condition ? color.red : na) // background coloring barcolor(condition ? color.red : na) // bar coloring ``` **na() Function:** ``` na(x) - returns true if x is NaN nz(x) - returns x if not NaN, else 0 nz(x, y) - returns x if not NaN, else y ``` **Ternary Operator:** ``` condition ? value_if_true : value_if_false ``` **VIDYA Implementation Detail (most critical for the user's use case):** ```lipi indicator("VIDYA", overlay=true) length = input(9, "Length") src = input(close, "Source") k = 2 / (length + 1) vol = abs(stdev(src, length) / sma(src, length)) vidya = na(vidya[1]) ? src : src * k * vol + vidya[1] * (1 - k * vol) plot(vidya, "VIDYA", color=color.green, linewidth=2) ``` The key self-referencing pattern is: `vidya = na(vidya[1]) ? src : ... vidya[1] ...` - On the first bar, `vidya[1]` is `na`, so it initializes to `src` - On subsequent bars, it uses the previous bar's value via `vidya[1]` This is the same pattern used in Pine Script and should work in Lipi Script. --- **FINAL SUMMARY:** I was unable to perform live web searches because my available tools are all Shoonya trading-platform specific (no web search, HTTP fetch, or file I/O tools). However, I compiled comprehensive Lipi Script documentation from training data knowledge covering: 1. **Syntax**: indicator(), plot(), input(), variables, self-referencing with `[n]`, `:=` reassignment, ternary operator 2. **Built-in math functions**: abs, max, min, sqrt, pow, round, log, exp, ceil, floor, sign 3. **Technical functions**: sma, ema, wma, rma, rsi, macd, atr, stdev, highest, lowest, crossover/crossunder 4. **talib functions**: Overlap (sma, ema, bbands, sar), Momentum (rsi, macd, stoch, adx, cci, willr), Volatility (atr, trange) 5. **Working examples**: VIDYA, RSI, EMA Crossover, Bollinger Bands, MACD 6. **Key pattern for self-referencing variables**: `na(vidya[1]) ? src : ... vidya[1] ...` **CAVEAT**: This is from training data, not verified against live GoCharting docs. The exact function signatures and available talib functions may differ. Recommend testing on the GoCharting platform directly.
