Create a custom Tradingview (Pine Script) indicator for alerts using two open source indicators

The indicators that will be used in this custom indicator are BIG SNAPPER - https://tradingview.com/script/56tr3OzQ-Big-Snapper-Alerts-R2-0-by-JustUncleL/ and Historical Volatility Percentile + SMA - https://www.tradingview.com/script/WQEK8atJ-Historical-Volatility-Percentile-SMA/. The goal of the indicator is to set notifications at the moment when all the conditions match.

Alert 1
- HVP > HVPSMA (by HISTORICAL VOLATILITY PERCENTILE indicator)
- Price above EMA (100)
- Long Line Marker appears (by BIG SNAPPER indicator)
- Candle is bullish (or if the candle is bearish, but the next candle is bullish)

Alert 2
- HVP > HVPSMA (by HISTORICAL VOLATILITY PERCENTILE indicator)
- Price below EMA (100)
- Short Line Marker appears (by BIG SNAPPER indicator)
- Candle is bearish (or if the candle is bullish, but the next candle is bearish)

The entire terms of reference is ready, I will share with the coder.
