With a mechanically actuated float, switching occurs as a result of the movement of a float against a miniature (micro) switch. For both magnetic and mechanical float level sensors, chemical compatibility, temperature, specific gravity (density), buoyancy, and viscosity affect the selection of the stem and the float.
In directed (or inverse) scanning, the indicator will only scan in the preset pattern when the user holds down a switch. Selections are made when the switch is released. [2] [9] In automatic (regular or interrupted) scanning, the indicator scans in the preset pattern on its own and item selection occurs when the scanner hits a switch. [5] [7]
The Technician, written for the IBM PC, helped investors analyze and chart broad market conditions using sentiment, momentum, and monetary indicators. MetaStock 1.0 was released in 1986. Both MetaStock and The Technician received PC Magazine ’s Editor’s Choice award in April 1986.
Liquid level floats, also known as float balls, are spherical, cylindrical, oblong or similarly shaped objects, made from either rigid or flexible material, that are buoyant in water and other liquids. They are non-electrical hardware frequently used as visual sight-indicators for surface demarcation and level measurement. They may also be ...
The indicator is trend-following, and based on averages, so by its nature it doesn't pick a market bottom, but rather shows when a rally has become established. Coppock designed the indicator (originally called the "Trendex Model" [1]) for the S&P 500 index, and it has been applied to similar stock indexes like the Dow Jones Industrial Average ...
An oscillator in technical analysis of financial markets is an indicator that informs if the price of a financial instrument is very high or very low, indicating whether it is overbought or oversold. This helps traders make decisions about when to trade (buy or sell) that instrument.
A fast EMA responds more quickly than a slow EMA to recent changes in a stock's price. By comparing EMAs of different periods, the MACD series can indicate changes in the trend of a stock. It is claimed that the divergence series can reveal subtle shifts in the stock's trend. Since the MACD is based on moving averages, it is a lagging indicator ...
The desk units would set up the ticker symbol code for the desired stock by mechanical means actuating micro switches. The local control box would continuously interrogate each desk unit in sequence and send a request data packet by Dataphone to the local drum memory which would then send return data packets back to the local brokerage office.
