Mql5官网 Resistance and Support Zones 外汇EA

The indicator uses a mechanical approach to identify resistance/support zones and assess their levels of strength showing which price zones are more important than others.

Resistance and Support are the main leading indicators used by most traders around the world. To be a successful trader, every trader needs to master the proper detection of price zones.

This indicator was created to avoid subjectivity rules when drawing support/resistance zones.

Most of the time, resistance and support are not a simple line dividing the price chart, but a price zone, where the market react when touching it.

The price action can perform a reversal or a breakout when reaching important price zones, thus generating trading opportunities.

Operation

The indicator searches for recent tops and bottoms to build the resistance/support zones.

After price zones are built, the indicator makes a clustering only for the overlapping price zones (tip: Avoid increasing so much the number of top/bottom parameter. It generally will result in larger price zones).

Finally, the indicator assesses the strength level for each price zone.

Automatic Strength Filter

A strength level of a zone is measured analyzing the price action when market reaches these price zones.

A price zone with a higher level of strength means that the price action tends to correspond strongly to this price area.

The indicator was built to analyze the strengths and weaknesses of a price zone, showing a level of strength for each zone drawn on a chart.

The trader could apply a strength level filter and the indicator will smooth the weaker price zones.

The following criterias are used to determine the level strength of a price zone:

• How many times the price zone worked as a barrier to the price advancing in the recent past.
• How many times the price used this area as a support or resistance in the recent past.
• How many times the price reacted strongly when reaching this price zone in the recent past.

Analyzing the criterias above, the indicator is capable to establish positive or negative points for each price zone.
