The Godson Advanced Crossover Script is advanced because it does two things
1: as a trend following indicator the script uses 2 VWAP[Volume weighted Average Price] ema's offset by 1 day(this is adjustable) and an ATR[Average true range] upper and lower band to find entries into larger trends.
2: it also allows you to setup alerts on a lower timeframe that follow a higher timeframe for example, if the 12hr is bearish(candles are red), you can trade shorts only in the 15min timeframe.
The script produces 3 signals
L: this is a long signal, this is signaled when the ema's crossover and the candle breakouts of the ATR bands, if the signal agrees with the upper trend S: this is a short signal, it signals when the ema's crossunder and the candle breaks down of the ATR bands, if the signal agrees with the upper trend H: this is for anything in-between, A is for apple, H is for Hedge.
you can set the upper trend timeframe to the same as the lower trend if you want all signals to alert
you can also turn the lines on or off if you need to visualize things
