Optimized SMA Crossover with VWAP, ADX Filter, and Dynamic S/R

Key Changes:
ADX Filter Enhancement: Added a check to ensure that the plusDI is greater than minusDI for a long signal and vice versa for a short signal. This ensures that the trend is in the direction of the crossover.

Removed Fake Signals: By ensuring that the crossover is in the direction of the trend (using plusDI and minusDI), we reduce the likelihood of false signals.

Consolidated Logic: The script now ensures that signals are only generated when the price is in a clear trend and the crossover is sustained.

This should help in reducing fake signals and provide more reliable buy/sell signals based on the SMA crossover, VWAP filter, and ADX trend strength.
