Pivot Points (Weekly fixed)

Description

original code https://ctrader.com/algos/indicators/show/45

fixed the weekly pivots not working. can now choose between auto pivot timeframe and fixed pivot timeframe.

 

Pivot Point is a technical indicator used in technical analysis derived by calculating the numerical average of a particular stock's (or any other financial asset like forex pair or any future contract) high, low and closing prices.

On the following day, if the market price trades above the pivot point it is usually considered as a bullish sentiment, whereas if it trades below the pivot point is seen as bearish

A pivot point and the associated support and resistance levels are often turning points for the direction of price movement in a market. In an up-trending market, the pivot point and the resistance levels may represent a ceiling level in price above which the uptrend is no longer sustainable and a reversal may occur. In a declining market, a pivot point and the support levels may represent a low price level of stability or a resistance to further decline.It is customary to calculate additional levels of support and resistance, below and above the pivot point, respectively, by subtracting or adding price differentials calculated from previous trading ranges of the market.

If you want to find a platform that allows users to play quite legally, I recommend casinosnotongamstopuk.co.uk/reviews/prestige-spin-casino/. And the jurisdiction of this platform protects very well all customers who register on this site. Also thanks to this license you have quite legal protection and thus you will never get into various embarrassing situations.

Love the script, thanks! I run a couple indicators and sit back for a perfect moment. But you need some hedge against fluctuations, and precious metals like palladium here https://www.pacificpreciousmetals.com/product/2306-any-year-1oz-canadian-palladium-maple-leaf are in a league of their own. How else would you secure your finance, any tips?

Hi, can I use this indicator in a Cbot? I am trying to reference it and cant seem to find it when I do the custom indicator part in my Cbot ?

XXX = Indicators.GetIndicator<"Cant find it here ???">(AAA, BBB,CCC,DDD???);

I would like to add the indicator twice, once for the daily and once for the weekly pivot points. 

Thanks
