Double Bottom and Top Chart Pattern w/ Support and Resistance

٢٧ يونيو ٢٠٢٣

-----------------------------------------------------------------
General Description:

This indicator (the one on the top panel) detects double top and double bottom patterns based on the “seasonality” of the classic MACD histogram (panel below) and the behavior of prices during those cycles.

Once a double top or a double bottom is confirmed the indicator draws a couple of parallel horizontal lines from both 1st and 2nd top or bottom, whichever be the case, and extend them horizontally all the way to the right of the chart. The indicator will keep drawing and extending the lines horizontally as many bars as the user indicates, leaving a clear demarcation of a possible support or resistance.

The indicator works on any market, any instrument, any timeframe, and any market condition.


-----------------------------------------------------------------
How it works:

The indicator tracks the values of the MACD histogram and prices. Every time the histogram is under 0 (during a negative cycle), the indicator detects and saves the minimum or more negative value of the price during that time/cycle/season. Every time the histogram is over 0 (positive cycle), the indicator detects and saves the maximum or more positive value of the price during that time/cycle/season.

Every time the histogram crosses over or under the 0 axis (every time a negative or positive cycle/season ends) the indicator makes its analysis.

When the histogram crosses over the 0 axis it means that a negative cycle just ended and the indicator begins to compare the minimum price registered during that negative cycle with the minimum price registered during the cycle before that last one (the last time the histogram was below 0). The indicator treats both minimum prices as “possible double bottoms” as long as they fit with our “deviation criteria”.

If the histogram crosses under the 0 axis it means that a positive cycle just ended and the indicator begins to compare the maximum price registered during that positive cycle with the maximum price registered during the cycle before that last one (the last time the histogram was above 0). The indicator treats both maximum prices as “possible double tops” as long as they fit with our “deviation criteria”.

Our deviation criteria is very simple, based on a relation between the average true range and the highs or lows. The MACD we use for the internal calculations is the standard (12, 26, 9).

After a double top/bottom is confirmed the indicator draws a couple of horizontal parallel lines from both tops/bottoms and extend those lines all the way to the right of the chart as many bars/candles as the user specifies, leaving a clear demarcation of a possible resistance or support.

Options/adjustments for this indicator:

*Deviation.
Refers to the difference/relation/vertical distance between the PRICE peaks involved in the double top/bottom.

*Double Top/Bottom min width.
Refers to the minimum horizontal distance between the peaks involved in the double Top/bottom.

*Double Top/Bottom max width.
Refers to the maximum horizontal distance between the peaks involved in the double top/bottom.

*Max bars back to extent line.
Maximum amount of bars back that the last double top/bottom peak was seen.

Among other visual options.

In this version the "select Timeframe" feature was included, which allows the user to see higher timeframe patterns while being still in lower timeframes. In the following example you can see the double top / bottom patterns and zones from the Weekly chart while being in the 4hour charts of SPY.
