This is a simple and reliable indicator. It was developed 8 years ago, but I still use it in my trading activity. It can be used both in manual trading and as a part of an Expert Advisor. The indicator works in two modes:

• By slow and fast МА crossing
• By slow МА's slope/fall angle. The parameter is set by SlowMADiffer variable allowing users to cut down the market "noise".

The value compared with SlowMADiffer variable can be used in the "speed counter"-like Expert Advisors showing how fast the price rises or falls. The function of the input fields is clear from variable names (see the screenshots).

Interpretation of the indicator readings is also quite intuitive (see the screenshots).
