How does a digital oscillator work?

An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave or a triangle wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal.

How do you use an oscillator?

If an investor uses an oscillator, they first pick two values; then, placing the tool between the two, the oscillator oscillates, creating a trend indicator. Investors then use the trend indicator to read current market conditions for that particular asset.
