Simple EMA Crossover Strategy

Calculates the 35-period and 100-period EMAs.
Detects when the EMA 35 crosses above (crossover_up) or below (crossover_down) the EMA 100.
Plots both EMAs on the chart for visual reference.
Implements the strategy logic:
Enters a long position when EMA 35 crosses above EMA 100.
Exits the long position when EMA 35 crosses below EMA 100.
Plots buy (green triangle) and sell (red triangle) signals on the chart.
