Cập nhật EMA21 Pullback Buy

EMA21 Pullback Buy is a tool designed to identify constructive pullbacks to the 21-period EMA in strong uptrends.
It highlights candles where:
• The previous close was above EMA21
• The current low touches or dips below EMA21
• The candle closes back above EMA21
These candles are considered potential “support tests” in a trending stock.
You can configure a maximum number of valid tests to avoid late-stage entries.
The script:
• Colors the test candles (optional)
• Marks them with a small circle
• Triggers a buy signal (green triangle) on the first bullish candle that breaks above the test candle’s high
Optional alerts are included for both:
• New EMA21 test
• Buy trigger after valid test
The goal is to help traders find low-risk entries in clean, trending stocks — without chasing breakouts or reacting emotionally. Best used with strong RS names and proper trend context.

Version: v1.1Date: 2025-12-11
What’s new:
🔹 Trend Sensitivity Option
You can now choose between three levels of trend strictness:
• Strict – Requires clear uptrend structure with slope and strength
• Moderate – Looser, still prefers alignment between EMAs
• Loose – Only checks that price is above EMA21
This allows you to adapt the indicator to different market conditions (e.g. choppy vs trending).
🔹 Optional EMA10 Momentum Filter
When enabled, the indicator will also require the 10 EMA to be rising, confirming short-term momentum.
This helps avoid noisy signals during weak consolidations or fake reversals.
🧠 These additions improve signal quality and give you better control over the type of pullbacks you want to trade.
No changes were made to entry logic or alerts.

🆕 Update: Optional Limit for Number of EMA21 TestsVersion: v1.2
Date: 2025-12-11
What’s new:
🔹 Configurable limit for EMA21 tests
Added a new setting:
Limit max number of EMA21 tests – when enabled, the script will only allow a defined number of pullback tests (default: 6) during a trend phase.
If disabled, all valid pullbacks will trigger, even late-stage entries in longer uptrends.
✅ This gives you more control:
• Want to focus only on early pullbacks? Keep it enabled.
