What this script says

Stochastic cross in extremes is an alert that checks every 1 hour, can fire every time its condition is met, waits 3 bars between alerts and shows where it fires on the chart.

It calculates `k_line` as the k of the stochastic and `d_line` as the d of the stochastic.

When `k_line` crosses above `d_line` and `k_line` is below 20, it sends the notification "Stochastic bullish cross at {k_line:0} on {market.symbol}".

When `k_line` crosses below `d_line` and `k_line` is above 80, it sends the notification "Stochastic bearish cross at {k_line:0} on {market.symbol}".
