The quadratic semaphore indicator is an indicator that find confirmed market u-turn with the help of 2 quadratic regressionĀ calculated with Highs and Lows over the last “length” periods.
“p” setting is candlesticks quantity to confirmed the quadratic regression has formed a High or Low parabola, such as Fractals. Consecutive same signals can happen due to the use of different price values for upper and lower semaphore.

Nicolas, trĆØs bien, en comparaison avec d’autres indicateurs de signaux trĆØs rapides.
Merci!
Dear Nicolas, congratulations for the good work. Does the indicator give the signals in real time or afterwards?
It gives signals afterwards. You can set the confirmation period with the p setting.
Dear Nicolas, is ita possible work on time-frame DAILY or the indicator Re-paint ?
Does the signal appear after a few some days?
The indicator does not repaint, given signals will not disappear, but signals appears indeed in the past when a parabola has been formed and confirmed.
Dear Nicolas, could you recommend some of your indicators that I can use on the Daily time-frame?
Thank you so muche for you help …
Thanks for this Nicolas… so, can this indicator be used in a strategy? eg using the dots as signals to buy/sell? I cant seem to work out how to use it in that way… thanks again
You can use it as signals or trend filters. Change the
Last line with: Return pivots,pivotl
New dots appear when one of these values has changed during the last candlestick.
Bonjour Nicolas,
thanks for this genius contribution and all the best for 2019.
I really like this indicator because it combines the powerful Regression and Williams Fractals concepts.
Since I donāt know how to use this indicator in an automated scalping strategy, I would appreciate it very much if you could advise how to do this in more detail (see question from āverybrubbyā)?
At least it would be great to understand how I can implement an acoustic signal (ābeep/bellā) in addition to the plot in the chart. I know how to define Alerts in PRT (https://www.prorealcode.com/blog/video-tutorials/alerts-prorealtime-10-3/) but using an indicator-based alert would be much more flexible.
Thanks a lot in advance and kind regards!
Please open a new topic if you need custom coding.
I like the look of this. I shall try it tomorrow.
Buenas tardes,me gustaria saber si tiene un proscreener de este indicador ,que busque los valores que marcan giro de mercado
Bonjour Nicolas
