Simple Buy/Sell Signals

The code works by continuously monitoring the relationship between two moving averages (MAs) on live price data — a fast MA (shorter period) and a slow MA (longer period). These MAs smooth out price action to help identify trends. Here's how it functions step-by-step:
Inputs: The user selects the MA type (SMA or EMA) and the lengths (periods) for the fast and slow MAs.
Calculation: The script calculates the chosen MAs using real-time closing prices.
Signal Logic: It detects a Buy signal when the fast MA crosses above the slow MA (crossover) and a Sell signal when the fast MA crosses below the slow MA (crossunder).
Plotting: When a signal occurs, the script plots a green "BUY" arrow below the candle or a red "SELL" arrow above it.
Alerts: It includes alert conditions so users can receive notifications when a buy or sell condition is met.
