[blackcat] L1 Mel Widner Auto Support and Resistance

Level: 1

Background

This indicator/formula was presented in the May 1998 issue of the ‘Technical Analysis of Stocks and Commodities’ magazine. The article was titled “Automatic support and resistance” the article described an approach to finding support and resistance levels on a chart.


Function

Support and resistance analysis is a proven method for selecting key price levels for trading decisions; traders usually perform the analysis by hand. The automatic charting method and new oscillators presented here are easy to implement and give a precise comparison of price to these important levels. Suppose prices are moving higher, fed by steady cash flow and favorable expectations. Then, at some point, the advance begins to slow. Upward momentum is still dominant, but at that point it is diminishing and the rate of rise is decreasing, evidence of resistance. It is like throwing a ball into the air; the ball starts with initial momentum, then slows under the influence of gravity before eventually falling.

Prices behave in a similar manner. After opposing resistance forces are applied for a time, prices slow, finally stop, and reverse direction. The turning point is a resistance level and is the highest high price for that particular period. The converse is true for declining prices. A slowing decline results from support forces and a support level is established at the point where prices turn upward.

Simply, forces cause acceleration. Market forces do not directly produce momentum, but rather momentum changes. These momentum changes in turn are integrated or accumulated to establish momentum. The presence of market forces is evident when the slope of prices, or momentum, changes over time. The effect is most dramatic when forces also change, triggered by price moves or changes in expectations, and abrupt reversals occur. Examination of price histories can confirm the presence of these features.

Two oscillators are defined: the WSO (Widner support oscillator) and the WRO (Widner resistance oscillator). The WSO compares the current close with the most recent six support levels. Values range from zero to 100. WSO = zero means that the close is below all of the six support levels, and
WSO = 100 means that the current close is above all of the six support levels. Changes in WSO indicate changes in support, either breaking of an old level or establishing a new one. The WSO abd WRO are defined as:

WSO = 100( 1 – (INT(S1/C) + INT(S2/C) + INT(S3/C) + INT(S4/C) + INT(S5/C) + INT(S6/C)) / 6)


WRO = 100( 1 – (INT(R1/C) + INT(R2/C) + INT(R3/C) + INT(R4/C) + INT(R5/C) + INT(R6/C)) / 6)


Consequently, WSO and WRO can cross, but this is very uncommon.
Enter long when support is strong and resistance is weak or enter when support is building.


Key Signal

wso --> Widner support oscillator.
wro --> Widner resistance oscillator.

Remarks

This is a Level 1 free and open source indicator.
