somebody1: when the macd change from + to - or vice versa,

How hard is it to get the macd value and compare it to the previous bar value? How hard is it to remember the time it occurred?

You say you "I have all code of the fractals," How hard is it to get time time that fractal occurred?

You say you "take the FIRST fractales post change of the macd." How hard it to compare both times to get your signal?

You have only three choices: Search for it, learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.
