Developed by Edson Gould, Speed Resistance Lines are trendlines based on 1/3 and 2/3 retracements. Gould was a prominent market technician who became quite famous for his market calls in the 60s and 70s. Gould appeared on Wall Street Week a few times and was often quoted in Barron's. Speed Resistance Lines are not drawn like traditional trendlines, which are based are peaks and troughs. Instead, the first line extends from the low to the high in an uptrend or from the high to the low in a downtrend. This first Speedline sometimes cuts right through prices. Subsequent lines are then placed at 1/3 and 2/3 intervals to estimate potential support or resistance levels. Gould also referred to Speed Resistance Lines as Speedlines.
Downtrend First Line: High to Low Middle Line: High to 2/3 point Upper Line: High to 1/3 point 2/3 point: High - (High - Low) x .667 1/3 point: High - (High - Low) x .333
Speed Resistance Lines work the same as ordinary trendlines. They can be used to estimate support or resistance levels and define the trend. In an uptrend, Speed Resistance Lines mark two potential support levels to watch. A break below the middle line targets a move towards the upper line. A break below the lower line indicates enough weakness to consider a trend reversal. Once broken, the line extensions can then mark resistance, just as ordinary trendlines. In a downtrend, Speed Resistance Lines mark two potential resistance levels to watch. A break above the middle line shows strength that targets a move to the upper line. A break above the upper line indicates a trend reversal. Once broken, these Speedlines can then turn into support on a pullback.
Chart 3 shows Target (TGT) with the Speed Resistance Lines drawn from the December low to the January high (yellow dots). Once drawn, these lines extend to the right as new price action occurs and new bars are added. This also means the support levels adjust and extend as well. It is also possible to redraw Speed Resistance Lines as new high form. TGT gapped down in early February, but the stock found support at the lower Speedline and continued its uptrend. The lower Speedline also provided support in late February and early May. Target broke below the lower Speedline in early June to signal a trend reversal. Notice how this line turned into resistance in mid June.
Chart 4 shows Pfizer (PFE) with the Speed Resistance Lines drawn from the June low to the July high. Despite such a short drawing period, the lower Speedline extension provided support in October and again in November. Also notice how the middle Speedline extension provided resistance in late August.
Chart 5 shows Macy's (M) with Speed Resistance Lines drawn from the October high to the December low. The first Speedline is marked with the yellow dots. The middle Speedline marks the first potential resistance level. The upper Speedline marks the second potential resistance level. Notice how Macy's broke above the middle Speedline with a strong surge in December, but hit resistance at the upper Speedline in late December and early January. The February break above the upper Speedline reversed the downtrend.
Chart 6 shows Electronic Arts (ERTS) with Speed Resistance Lines extending from the June high to the September low. ETRS broke above the middle Speedline, but met resistance at the upper Speedline in mid October. After a sharp decline into December, the stock found support near the middle Speedline. This is a classic example of how Speedlines can offer resistance before a breakout and support after a breakout. It depends on the location of price. ERTS bounced again, but again met resistance just below the upper Speedline.
Speed Resistance Lines can be repositioned as a security extends its trend with lower lows or lower highs. In the Electronic Arts example below, the first Speedlines were based on the June high and September low. ERTS forged new lows in December and again in February as the downtrend extended. The first Speed Resistance Lines are blue and the second Speed Resistance Lines are pink. Speedlines for the December low were skipped to keep the chart relatively clean. Notice how the Speedlines widened as the stock forged lower lows. This is because the length of the move from high to low grew larger - as did the 1/3 and 2/3 retracements. The repositioned Speed Resistance Lines (pink) were based on the June high and February low. Even though the stock broke above its January high, the upper Speedline extension marked resistance in April.
Speed Resistance Lines divide the trend into three sectors, or thirds. This is similar to Fibonacci retracements, which are based on 38.2% and 61.8%. In addition, Dow Theory suggests that securities retrace 1/3 to 2/3 of an advance or decline with a corrective move. Applying Speed Resistance Lines after an advance or decline provides chartists an immediate idea of where to expect support or resistance. These Speedlines can be maintained as is or repositioned as an advance or decline extends with new highs or low. Repositioning after a higher high or lower will widen the Speed Resistance Lines. This means potential support or resistance levels will be further away. As with all indicators and line studies, Speed Resistance Lines should be used in conjunction with other aspects of technical analysis. They are not designed as stand alone indicators.
Speed Resistance Lines can be accessed when annotating a Sharpchart. First, open the annotation window. Second, hover over the trendline icon in the upper left corner. This icon is square with a mini trendline going from the upper left to the lower right. Hovering over this icon will put the Speed Resistance Lines icon in view and users can then click to select. Third, move the pointer/mouse to the starting point, click and hold down on that click. Fourth, drag the pointer/mouse to the desired endpoint and release. The Speed Resistance Lines will appear. Once on the chart, users can move them around by clicking and dragging the starting or ending points.
This book covers Speed Resistance Lines and many other trendline tools including internatl trendline, channels and the fan principle.
