The script uses 3 simple moving averages that you can define (SMA Top, SMA Mid, SMA Long).
Once the SMA Top is above the SMA Mid and the SMA Mid is above the SMA Top a long position is entered.
Once the SMA Top is below the SMA Mid and the SMA Mid is below the SMA Top a short position is entered.
You may define how long before these positions are entered by adjusting the bars in the Inputs section.
A setting of 0 will enter a position as soon as the conditions are met,
whereas a setting of 5 will wait 5 bars after the conditions are met before entering the positions.
