Spread Analyser

Spread Analyser - a simple, but useful indicator that displays and analyzes the history of the floating spread from your broker.

While many brokers claim that they provide low spread, they often indicate the average value does not denote maximum the value of the spread of the day. Quite often instantaneous spread can reach "peak" is several times higher than the average. If these peaks arise in the environment of high volatility (as is often the case), they can significantly affect your trading strategy.

On the other hand, since the spread is the main way to achieve protection and broker profits, it is likely that the behavior of the spread may portend strong movements / price volatility, or at least to be a good indicator for input / output.

These motifs formed the basis for the development of this indicator.

Indicator collects spread values ​​for each incoming tick and evaluates the maximum, minimum and mean value within each bar, and then displays these values ​​by lines in a separate window. At the same time, in the main chart window, these values ​​are displayed with reference to the entire history of the schedule.

After a few days of data collection, the trader can reliably judge the quality of a broker on the importance index actual Spread policy. In addition, the trader may detect possible correlations, for example, the level of volatility, volume, strength of the trend, etc.

The indicator can be used on any timeframe.

This (paid) version of the history of the spread can be stored in an external file, so that the collected historical data is not lost, you can re-download the chart every time you restart the indicator.
