RSI Combo: Buy + Sell + COMBO

ONLY FOR CRYPTO ASSETS!

This script generates RSI-based Buy and Sell signals for the current asset, with optional confirmation from the USDT Dominance index (USDT.D).

🔍 Logic Overview:
A Buy signal is triggered when:

RSI is below a defined threshold (default: 21)

Price is below the EMA (default: 100)

A Sell signal is triggered when:

RSI is above a defined threshold (default: 80)

Price is above the EMA

🔁 Combo Signals:
If a signal on the main asset is confirmed by an opposite signal on USDT.D (inverse logic), the script replaces the standard signal with a "combo" version:

combo buy = Buy signal on asset + Sell signal on USDT.D

combo sell = Sell signal on asset + Buy signal on USDT.D

This confirms a risk-off to risk-on (or vice versa) shift in the market.
