lucy EMA 50 High & EMA 20 Low

Technical Description (Code Functionality)
This Pine Script calculates and displays:

✅ 1. EMA 50 of the High Price
ema50High = ta.ema(high, 50)

This is the 50-period Exponential Moving Average (EMA) calculated using the high price of each candle.

It reacts slower than shorter EMAs, smoothing out short-term noise to help identify broader trend direction using the upper extremes of price.

✅ 2. EMA 20 of the Low Price
ema20Low = ta.ema(low, 20)

This is a 20-period EMA calculated using the low price of each candle.

Being shorter in length, it reacts faster to price changes, showing short-term momentum or pressure, but based on lower extremes of price.

✅ 3. Plotting and Visualization
Both EMAs are plotted on the chart using different colors:

Orange for EMA 50 High

Blue for EMA 20 Low

There's also a gray shaded area ("zone") filled between the two EMAs to visually highlight the range or channel created by these two levels.

📈 Trading Interpretation
This setup can be used in several ways, depending on strategy:

🔍 Trend Filter
If price stays between or above the EMA 50 High and EMA 20 Low, it may indicate an uptrend with strength and follow-through.

If EMA 20 Low crosses below EMA 50 High, it might suggest weakening bullish momentum or a potential trend reversal.

🟩 Buy Zone Concept
Some traders interpret the space between these EMAs as a potential entry zone in uptrends:

Price pulls back toward the EMA 20 Low (support) but doesn't break below EMA 50 High — this could signal a buy-the-dip opportunity.

🟥 Sell Signal / Bearish Shift
If price closes below both EMAs, or if EMA 20 Low crosses below EMA 50 High, it could be a signal for:

Exit

Short entry

Trend weakening

🛡️ Risk Management Tips
Avoid trading just on the crossover; use this with volume, MACD, RSI, or price action confirmation.

Place stop-loss below the EMA 20 Low (for long entries) to account for volatility.

Use EMA crossbacks (where EMA 20 re-crosses above EMA 50) as confirmation for re-entry.
