I need a function code for my EA!

Hi,

I NEED A FUNCTION CODE THAT CAN GIVE ME THE BELOW 2 INFORMATION.

(1) Price of symbol at the time when Stochastic oversold is over and Stochastic is just crossed up the level of 20  or Stochastic Overbought is over and Stochastic has just crossed down the level 80.

(2) Total number of candles formed since Stochastic oversold is over and stochastic has just crossed above level 20 OR Stochastic Overbought is over and Stochastic is just crossed down Level 80.

Function should return 2 values (Price and number of candles)

Please see attached screenshot and let me know if you need any clarification.
