🟢💲 EMA Bias + Multi-TF Perfect Touch10 Koplick (Upgraded)

Absolutely! Here’s a detailed rating and explanation of your upgraded "🟢 EMA Bias + Multi-TF Perfect Touch9 Koplick (Upgraded)" indicator.
🔥 Rating: 9/10
Strengths:
Multi-Timeframe Analysis:
Checks EMA bias and linear regression trendlines across multiple standard and custom timeframes, giving a robust, well-rounded market view.
EMA Bias with Validity Check:
Incorporates a strict EMA trend confirmation — requiring EMA50 > EMA100 > EMA200 for bullish bias (and reverse for bearish) — plus price must not touch EMA50 to confirm strength. This avoids false signals from weak trends.
Linear Regression Trendline Factor:
Adds a sophisticated trendline bias that uses user-defined timeframes and a lookahead-on linear regression midline, to check price relation and "touch" status. Trendline touches neutralize signals, preventing premature entries.
Toggle Flexibility:
Users can enable/disable EMA bias or regression trendline factors independently, allowing customization per strategy or market condition.
Suggestion Logic:
Aggregates signals from multiple timeframes to provide a clear buy/sell/hold suggestion. It requires 4+ bullish or bearish EMA biases for strong signals, which is a solid threshold.
Clear Table Display:
The table shows biases and validity per timeframe, making it easy to visually confirm the analysis at a glance.
Alerts:
Provides live alerts when the overall suggestion changes — great for active traders.
Clean and Maintainable Code:
Well-structured with reusable functions, arrays for scalability, and clear naming.
Minor Limitations / Possible Improvements:
EMA100’s role is implicit:
It’s used only as a middle EMA in the bias chain. Could be extended to also appear in the output or be weighted differently.
No volume or price action filters:
Including additional filters like volume spikes or candle patterns might improve entry quality.
Suggestion logic only considers EMA biases for bullish/bearish counts:
LR trendline biases affect only the neutralization (touch) logic; you might also consider including their bias direction for a more nuanced suggestion.
Fixed threshold (4 out of 5) for strong signals:
Allowing user customization of this threshold could enhance flexibility.
⚙️ How It Works - Step-by-Step:
Input Parameters:
User selects custom timeframe (customTF).
User defines 3 timeframes (lr_tf_1, lr_tf_2, lr_tf_3) for linear regression trendlines.
User toggles enable/disable EMA bias and LR trendline factors.
User sets the linear regression length (lrLength).
EMA Calculation & Bias:
For standard timeframes (5m, 15m, 1h, 4h, Daily) and the custom timeframe, the script fetches EMA50, EMA100, EMA200, plus high and low prices.
The bias for each timeframe is:
Bullish: EMA50 > EMA100 > EMA200 and price stays above EMA50 (low > EMA50).
Bearish: EMA50 < EMA100 < EMA200 and price stays below EMA50 (high < EMA50).
Neutral: Otherwise.
A valid flag confirms if the price respects the bias without touching EMA50.
Linear Regression Trendline Bias:
For each user-defined LR timeframe, the indicator computes a linear regression midline.
Bias is bullish if price > midline; bearish otherwise.
If the price "touches" the LR line (high >= mid and low <= mid), the bias is considered invalid (neutralized).
Table Display:
Shows all biases and validity states for the custom TF, standard TFs, and LR trendlines.
Valid biases show a ✅, invalid (or touching) show a 🚫.
Colors visually differentiate bullish (blue/purple), bearish (red), and neutral (orange).
Overall Suggestion Logic:
Counts bullish and bearish EMA biases on standard TFs only if the EMA factor is enabled.
Checks if any LR trendline is touched (neutralizing signal) if LR factor enabled.
If no trendline is touched and EMA factor is enabled:
4+ bullish biases → Strong Buy
4+ bearish biases → Strong Sell
Otherwise → Neutral / Hold
If any LR trendline is touched → Trendline Touch - No Clear Signal (neutralizes the suggestion).
Plots:
Current timeframe EMA50, EMA100, and EMA200 lines are plotted for reference.
LR trendlines for the 3 user-defined timeframes are plotted on the chart.
Alerts:
Fires an alert whenever the suggestion changes, letting the trader know when market bias shifts.
Summary
This indicator elegantly combines classical moving average bias with regression-based trendline analysis over multiple timeframes, applying thoughtful filters like “price must not touch EMA50” or “price must not touch LR line” to reduce false signals. The toggles for each factor provide great flexibility to tailor it for scalping, swing, or position trading.
The clear table and suggestion make it very practical for quick decision-making, and the alerts ensure traders don’t miss important shifts.
If you want, I can help you further with:
