New type of signal for oscillators

Hello everyone, hello Andrey! I suggest adding a new type of signal for oscillators.

For example:

- To open BUY or to close SELL - Stochastic K must be lower than LevelDn value and form a "V", (stoch[0] > stoch[1] && stoch[1] < stoch[2]).

- And vice versa. 

I think that in this way, when optimizing, we will be able to find better entrances and exits.

Thank you in advance for your consideration.
