Comparator

This indicator compares the price changes during the specified period for the current symbol and other reference symbol. It allows to analyze the similar movements of highly correlated symbols, such as XAUUSD and XAGUSD, and find their occasional convergences and divergences for trading opportunities.

The indicator displays the following buffers:

  • light-green thick line - price changes of the current symbol for TimeGap bars;
  • light-blue thin line - price changes of the reference symbol (LeadSymbol) for TimeGap bars;
  • yellow dotted line - the difference between these two lines;
  • red histogram - buy (positive) or sell (negative) signals on bars where the difference is greater than the value of PriceGap points of the current symbol;

Price changes are calculated as value/profit/loss (in the account currency, or in USD if not connected) of buying 1 lot of the current symbol between TimeGap bars ago and the current bar.


Parameters

  • LeadSymbol - the reference symbol to compare with the current; default - empty string - comparison is not performed;
  • TimeGap - time period (number of bars) to use in the analysis of joint movement; default - 50;
  • PriceGap - threshold for buy and sell signals, when the difference between current and reference symbol price changes exceeds the value of PriceGap points for 1 lot of current symbol; the value of the specified PriceGap points is output to the log;
  • Inverse - enable/disable explicit inversion of the reference symbol prices; default - false; if true - overrides the Autodetect setting;
  • Autodetect - enable/disable automatic detection of direct or inverse relation of current symbol and reference symbol; default - true;
  • ScalingMode allows to additionally scale the chart of the reference symbol according to the ratio of the monthly volatilities of the symbols (1) or required margins ratio (2); When ScalingMode is set to 3, the scaling mode based on the ratio of the price change percentage is used; when the mode 3 is enabled, the minimum difference between the symbols in percents (for example, 0.01 for 1%) should be specified in the ScalingHint parameter as the threshold for signal generation. It is also possible to set a custom scaling coefficient in the ScalingHint parameter, where a hint on scaling is initially displayed. For this to work, the ScalingMode must be equal to 4;
  • MA, if not 0, enables the use of smoothing of the specified period during the price calculation of the TimeGap bar. By default, MA=0, and the bar closing prices are used, similar to the first version;
  • Notification parameters for the formation of new signals (red histogram) and zero level crossing by the difference lines (yellow dotted): EnableNotifications (enable/disable flag), SignalSound (sound file name), ZeroCrossingSound (sound file name). If the sound files are not specified (blank), an Alert is displayed. If the sound file is specified, it is played instead of the alert. Signals are generated on newly closed first bars.

Please note, that comparison of most Forex symbols will effectively display their crosses (if they exist). Thus, comparison only makes sense for the pairs that are interdependent, i.e. the dependent symbol repeats the movements of the reference symbol (to some extent). During the analysis of such pairs, make sure to select the correct analysis direction, i.e. the indicator is located on the chart of the dependent symbol and the leading symbol is selected as the reference symbol and not vice versa. Otherwise, inverted signals will be received.

This is one of the very few indicators on the market that's actually purposeful!

Don't give a negative review simple because you don't know how to use it.

Version 1.5 - 2016.06.13
Fixed an error in the calculation of the relative scaling of symbols with ScalingMode set to 1 (by volatility).
Version 1.4 - 2015.11.19
New parameters added for notifications on new signals (red histogram) and zero crossings by difference line (yellow dotted): EnableNotifications (enable/disable flag), SignalSound (sound file name), ZeroCrossingSound (sound file name). If sounds are empty, alert is shown. If a sound is specified, it's played without an alert. Signals are created on just closed 1-st bar.
Version 1.3 - 2014.07.22
- Improved scaling in volatility mode;
- Added new mode of scaling: by ratio of price percentage change; to use it, specify 3 in ScalingMode (former scaling mode by custom coefficient is "moved" from 3 to 4); when the mode 3 is enabled, the threshold for divergence signals should be specified in ScalingHint as a minimal difference between symbols in percentage terms, for example, 0.01 for 1%.
Version 1.2 - 2014.07.10
Fixed "array out of range" error.
Version 1.1 - 2014.07.08
- Fixed bar synchronization problem.
- Added new parameters: ScalingMode and MA.

ScalingMode allows applying additional scaling for the leading symbol either by monthly volatilities ratio (1), or required margins ratio (2). Also a custom scale coefficient can be specified in ScalingHint parameter, where initially a hint about scaling is shown. This works when ScalingMode is 3.

When MA parameter is greater than 0, a smoothing of the given period is applied for the calculation of prices at bars with TimeGap offset. By default, MA=0, and close prices of the bars are used, in the same way as it was in the version 1.0.
