Bull and Bear Fear Expert by Walter Downs Strategy

can you made alert version?

Buongiorno, qualcuno mi spiega come funziona questo indicatore, che non riesco a comprenderne i meccanismi e l'applicazione pratica? Sarei interessato, grazie

@Cripto1, grazie,
Bull Fear/ Bear Fear
The system is a trend follower that appears to get you in at the early in a trend. If the trend breaks down for any reason, the system seems to take you out with relatively little pain, and there is a relatively high
percentage of losing trades (usually around 50%).
Therefore, the system seems to perform best on issues that are prone to make prolonged moves.

@ceyhun, Thank you. Some questions...
So does the system have a 50% false signal rate? And the strange coloring of the candles, how should it be read? And how should the scripts "-2 short" and "long +2" be interpreted? What do those "+2" and "-2" mean?

@Cripto1, bull blue
red bear
change time gray

Event calculation method you call -2, + 2 ...

BullFear = (highest (high, n) -lowest (high, n)) / 2 + lowest (high, n)
BearFear = (highest (low, n) -lowest (low, n)) / 2 + lowest (low, n)

@ceyhun, Interesting. So, when, exactly, I should buy or sell by following the signals provided by the system? For example i see the system provides a couple of arrows over or under and bisides some candles...

@Cripto1,

The important thing is to find a trend, all indicators are forced horizontally.
Since it is a strategy, it gives 1 bar late.

@ceyhun, I understood everything. I wait for my great-grandchildren to grow, in 20 years maybe some of them, if interested in trading, will be able to explain to me how this indicator works. I must confess to you that your explanations, however kind, are and remain, for me indecipherable.In fact, I continue to ask you specific questions which you, in your reply, continually evade. Excuse me, you know, but if I ask you to explain a specific thing, you cannot give me in response concepts not pertinent to the question ...So, i'll continue to respond you i've all understood while understanding nothing....

@Cripto1, I find if you increase the time period to 30 that it works better on the higher time frames. You just need to have a system on top of this system to filter out the false signals, say something like whipsaws.

@JasonLeighton, And, apologize my ignorance, "what are these whipsaws?"
Thank you....
