iD EMARSI on Chart

3월 15일

SCRIPT OVERVIEW
The EMARSI indicator is an advanced technical analysis tool that maps RSI values directly onto price charts. With adaptive scaling capabilities, it provides a unique visualization of momentum that flows naturally with price action, making it particularly valuable for FOREX and low-priced securities trading.

KEY FEATURES

1 PRICE MAPPED RSI VISUALIZATION
Unlike traditional RSI that displays in a separate window, EMARSI plots the RSI directly on the price chart, creating a flowing line that identifies momentum shifts within the context of price action:

// Map RSI to price chart with better scalingmappedRsi = useAdaptiveScaling ?     median + ((rsi - 50) / 50 * (pQH - pQL) / 2 * math.min(1.0, 1/scalingFactor)) :     down == pQL ? pQH : up == pQL ? pQL : median - (median / (1 + up / down))

2 ADAPTIVE SCALING SYSTEM
The script features an intelligent scaling system that automatically adjusts to different market conditions and price levels:

// Calculate adaptive scaling factor based on selected methodscalingFactor = if scalingMethod == "ATR-Based"    math.min(maxScalingFactor, math.max(1.0, minTickSize / (atrValue/avgPrice)))else if scalingMethod == "Price-Based"    math.min(maxScalingFactor, math.max(1.0, math.sqrt(100 / math.max(avgPrice, 0.01))))else // Volume-Based    math.min(maxScalingFactor, math.max(1.0, math.sqrt(1000000 / math.max(volume, 100))))

3 MODIFIED RSI CALCULATION
EMARSI uses a specially formulated RSI calculation that works with an adaptive base value to maintain consistency across different price ranges:

// Adaptive RSI Base based on price levels to improve flowadaptiveRsiBase = useAdaptiveScaling ? rsiBase * scalingFactor : rsiBase// Calculate RSI components with adaptivityup = ta.rma(math.max(ta.change(rsiSourceInput), adaptiveRsiBase), emaSlowLength)down = ta.rma(-math.min(ta.change(rsiSourceInput), adaptiveRsiBase), rsiLengthInput)// Improved RSI calculation with value constraintrsi = down == 0 ? 100 : up == 0 ? 0 : 100 - (100 / (1 + up / down))

4 MOVING AVERAGE CROSSOVER SYSTEM
The indicator creates a smooth moving average of the RSI line, enabling a crossover system that generates trading signals:

// Calculate MA of mapped RSIrsiMA = ma(mappedRsi, emaSlowLength, maTypeInput)// Strategy entriesif ta.crossover(mappedRsi, rsiMA)    strategy.entry("RSI Long", strategy.long)if ta.crossunder(mappedRsi, rsiMA)    strategy.entry("RSI Short", strategy.short)

5 VISUAL REFERENCE FRAMEWORK
The script includes visual guides that help interpret the RSI movement within the context of recent price action:

// Calculate pivot high and lowpQH = ta.highest(high, hlLen)pQL = ta.lowest(low, hlLen)median = (pQH + pQL) / 2// Plottingplot(pQH, "Pivot High", color=color.rgb(82, 228, 102, 90))plot(pQL, "Pivot Low", color=color.rgb(231, 65, 65, 90))med = plot(median, style=plot.style_steplinebr, linewidth=1, color=color.rgb(238, 101, 59, 90))

6 DYNAMIC COLOR SYSTEM
The indicator uses color fills to clearly visualize the relationship between the RSI and its moving average:

// Color fills based on RSI vs MAcolUp = mappedRsi > rsiMA ? input.color(color.rgb(128, 255, 0), '', group= 'RSI > EMA', inline= 'up') :                    input.color(color.rgb(240, 9, 9, 95), '', group= 'RSI < EMA', inline= 'dn')colDn = mappedRsi > rsiMA ? input.color(color.rgb(0, 230, 35, 95), '', group= 'RSI > EMA', inline= 'up') :                    input.color(color.rgb(255, 47, 0), '', group= 'RSI < EMA', inline= 'dn')fill(rsiPlot, emarsi, mappedRsi > rsiMA ? pQH : rsiMA, mappedRsi > rsiMA ? rsiMA : pQL, colUp, colDn)

7 REAL TIME PARAMETER MONITORING
A transparent information panel provides real-time feedback on the adaptive parameters being applied:

// Information displayvar table infoPanel = table.new(position.top_right, 2, 3, bgcolor=color.rgb(0, 0, 0, 80))if barstate.islast    table.cell(infoPanel, 0, 0, "Current Scaling Factor", text_color=color.white)    table.cell(infoPanel, 1, 0, str.tostring(scalingFactor, "#.###"), text_color=color.white)    table.cell(infoPanel, 0, 1, "Adaptive RSI Base", text_color=color.white)    table.cell(infoPanel, 1, 1, str.tostring(adaptiveRsiBase, "#.####"), text_color=color.white)

BENEFITS FOR TRADERS

INTUITIVE MOMENTUM VISUALIZATION
By mapping RSI directly onto the price chart, traders can immediately see the relationship between momentum and price without switching between different indicator windows.

ADAPTIVE TO ANY MARKET CONDITION
The three scaling methods (ATR-Based, Price-Based, and Volume-Based) ensure the indicator performs consistently across different market conditions, volatility regimes, and price levels.

PREVENTS EXTREME VALUES
The adaptive scaling system prevents the RSI from generating extreme values that exceed chart boundaries when trading low-priced securities or during high volatility periods.

CLEAR TRADING SIGNALS
The RSI and moving average crossover system provides clear entry signals that are visually reinforced through color changes, making it easy to identify potential trading opportunities.

SUITABLE FOR MULTIPLE TIMEFRAMES
The indicator works effectively across multiple timeframes, from intraday to daily charts, making it versatile for different trading styles and strategies.

TRANSPARENT PARAMETER ADJUSTMENT
The information panel provides real-time feedback on how the adaptive system is adjusting to current market conditions, helping traders understand why the indicator is behaving as it is.

CUSTOMIZABLE VISUALIZATION
Multiple visualization options including Bollinger Bands, different moving average types, and customizable colors allow traders to adapt the indicator to their personal preferences.

CONCLUSION
The EMARSI indicator represents a significant advancement in RSI visualization by directly mapping momentum onto price charts with adaptive scaling. This approach makes momentum shifts more intuitive to identify and helps prevent the scaling issues that commonly affect RSI-based indicators when applied to low-priced securities or volatile markets.

[h1]Overview of EMARSI Strategy[/h1]

[h2]Signal Generation[/h2]
The script now generates signals based directly on RSI/MA crossovers:
- Bullish Signal: When mapped RSI crosses above its MA
- Bearish Signal: When mapped RSI crosses below its MA
- Option to require minimum trend duration before triggering

// Detect crossoversbullishCross = ta.crossover(mappedRsi, rsiMA)bearishCross = ta.crossunder(mappedRsi, rsiMA)// Simplified signal generationbool validBullishSignal = bullishCross and (not useFilteredSignals or bearishTrendBars >= minTrendDuration)bool validBearishSignal = bearishCross and (not useFilteredSignals or bullishTrendBars >= minTrendDuration)

[h2]Key Components[/h2]
- Custom RSI calculation with adaptive scaling options
- Mapped RSI that aligns the indicator with price chart
- Simple moving average of the mapped RSI for crossover detection
- Trend duration tracking to filter signals

// Calculate RSI components with adaptivityup = ta.rma(math.max(ta.change(rsiSourceInput), adaptiveRsiBase), emaSlowLength)down = ta.rma(-math.min(ta.change(rsiSourceInput), adaptiveRsiBase), rsiLengthInput)// RSI calculation with value constraintrsi = down == 0 ? 100 : up == 0 ? 0 : 100 - (100 / (1 + up / down))// Map RSI to price chartmappedRsi = useAdaptiveScaling ?     median + ((rsi - 50) / 50 * (pQH - pQL) / 2 * math.min(1.0, 1/scalingFactor)) :     down == pQL ? pQH : up == pQL ? pQL : median - (median / (1 + up / down))

[h2]Visualization Elements[/h2]

[h2]Information Display[/h2]
- Current scaling factor and RSI base values
- Current trend direction and duration
- Total bullish and bearish signals generated

// Information displayvar table infoPanel = table.new(position.top_right, 2, 6, bgcolor=color.rgb(0, 0, 0, 80))if barstate.islast    table.cell(infoPanel, 0, 2, "Current Trend", text_color=color.white)    table.cell(infoPanel, 1, 2, mappedRsi > rsiMA ? "Bullish" : "Bearish",         text_color=mappedRsi > rsiMA ? bullSignalColor : bearSignalColor)    table.cell(infoPanel, 0, 3, "Trend Duration", text_color=color.white)    table.cell(infoPanel, 1, 3, str.tostring(mappedRsi > rsiMA ?         bullishTrendBars : bearishTrendBars), text_color=color.white)

[h2]Recent Fixes[/h2]
- Fixed plotshape syntax to be compatible with Pine Script v6
- Removed complex staging system in favor of direct signals
- Simplified codebase for better performance and clarity
- Added toggle options for better control over visualization

// Fixed plotshape calls// OLD (causing errors):// plotshape(showSignalMarkers and validBullishSignal ? true : na, ...)// NEW (fixed for Pine v6):plotshape(showSignalMarkers and validBullishSignal, ...)

The strategy is now focused solely on generating signals from RSI/MA crossovers, making it easier to understand and more reliable in signal generation.
