NEMA Acronyms & Symbols

__________________________________________________________________________________________________ Many of the below acronyms appeared in earlier charts that are still shown in some of the above futures links.

A-T, auto trend, "336 Trend"	A short term trend indicator based on the last 4 days of data has been shown to be very reliable. It is used in the most recent displays. See the "Equations" link for the A-T calculations.
B/S	Buy or sell (signals).
CB, L	Daily NEMA contracts bought.
CS, S	Daily NEMA contracts sold.
CB11, CB8	Contracts bought, smoothed. The number indicates how many days of data are used in the average. Normally, the endpoint moving average (EPMA) is used. Other names for EPMA are linear regression and least squares curve fit.
CBs8	8 day slope of the daily contracts bought. See "Equations" link.
CSs8	8 day slope of the daily contracts sold.
CS4	4 day EPMA of daily contracts sold.
Chart Titles	ALL: Earlier charts that showed close price and several indicators together on one chart using y-axis translation to a common scale. The y-axis translator is used extensively on most charts to show trends, B/S signals, etc., relative to the daily close price. NBBS: Chart summarizes buying and selling activity and net buying divergence with price, to help in determining candidate B/S signals. The chart is also used to evaluate new indicators. In the past they have been evolutionary and different for different futures, but with recent success have converged to a common few. The previous charts (CBBS) show this evolutionary development for many of the futures. HLC: Daily high, low, and close price. INTERNALS: Earlier charts that showed daily net buying, net selling, long activity, and short activity in NEMA contracts. Slopes of these variables were also plotted. The small "s" signifies slope. The resulting daily close price curve was also shown. LASA: Features the cLASA indicator and its relationship to other indicators and price. NB: Shows net buying, using different smoothing periods. ROLL: Rollover chart showing lead volume, lead OI, total volume, and total OI. Recent use is limited to the SP contract. STRUC: Structure chart showing accumulated longs, shorts, and key indicators relative to price. TRENDS: In earlier work various calculated trends were shown on one chart. Some trends are now shown on the NBBS charts. Price & OI: Price and OI plotted together to show the basis of the net NEMA activity. cL vs CL PRICE: Recent charts show the relationship between cumulative longs and the close price. The comparison has not been of much benefit..
cNBraw, cNB	Accumulated daily net buying (NB); raw data, not smoothed, in NEMA contracts.
cNB11	11 day EPMA of accumulated daily NB.
CL	Close price.
CL TREND	Short term trend of closing price. See the "Equations" link for the spreadsheet equation.
CLC	Continuous Lead Contract. Calculated volume weighted values only exist during the active portion of rollover. Values before and after the CLC rollover are actual contract values.
cLONGS, cL	Cumulative daily NEMA longs, unfiltered.
cSHORTS, cS	Cumulative daily NEMA shorts, unfiltered.
CME RTH	Chicago Mercantile Exchange regular trading hours data; no night Globex price included. Used for SP only because of its role in stock index arbitrage (with SPX). Because of this, SP is a key driver for all markets. Note that index arb selling coupled with other "program selling" causes flash crashes, and previous crashes like the Oct 87 crash. And it still can.
JRs	An indicator based on accumulated net buying.
JR system	A multi-NEMA indicator system that takes into account the shape of the price curve.
LASA, cLASA	An indicator that results from the difference in buying and selling volatilities.
L8, S8	8 day EPMA of daily NEMA long activity and short activity.
L4, S4	4 day EPMA of daily NEMA long activity and short activity.
MDI	More Down Indication for price. Sometimes used with NB or other NEMA indicator divergences with price.
MUI	More Up Indication for price..
NB	Daily net buying in NEMA contracts. When negative, it indicates net selling.
NBraw,4,8,11	4 values of NB plotted on the same chart; raw and 4, 8, and 11 day EPMA's of NB.
4NBraw	4 day moving sum of daily raw NB (~ 4 day moving integral).
2NB8	2 day moving sum of 8 day EPMA of NB.
NBTI	Net buying trend indicator. An overall trend indication that plays well with NB11 A-T for sideways market signals.
NVs	A net volatility indicator that is based on cLASA. .
cNB%V	Accumulated NB expressed as a per cent of daily volume. Daily NB as a percentage of the volume (NB%V) is shown on many recent charts.
RTH	Regular trading hours.
Vortex11, V11 V11+, V11-	V11 = the Vortex Indicator, configured for 11 days. It was developed by Etienne Botes and Douglas Siepman. It is similar to the directional movement indicator developed by J. Welles Wilder in its computation, but it is based on a unique usage of price highs and lows. The Vortex is nice to have on display to provide a warm “trend confirmed” feeling. But when compared with NB11 and cLASA auto-trends (A-T), the "V11+ A-T" has more delay in showing short term trend changes. Also, the peaks and valleys of the close price correlate well with the null crossovers of the NEMAC LS indicator. The V11 has more lag relative to price, than the LS indicator. This is easily seen in the following comparison. See examble. For details, see "Botes, Etienne and Siepman, Douglas [2010]. “The Vortex Indicator,” Technical Analysis of STOCKS & COMMODITIES, Volume 28: January."
