Charts Synchronizer 外汇EA

The “Chart synchronization” utility (the SynchronizeCharts indicator) can help traders in simultaneous trading on multiple financial
instruments, as it automatically scrolls all or selected charts of the terminal according to the position of the master chart. 

Four charts are shown in the screenshot 1. The EURUSD chart is the master chart, as the SynchronizeCharts indicator is attached to it. As a
result, the other three charts are displayed on the timeline starting from 2017.02.17 23:15. Any further movement of the EURUSD chart along
the timeline will cause a corresponding movement of the slave charts.

Corresponding bar line

A corresponding bar line – vertical blue line is displayed on the slave charts by default. It shows the exact time at which data display
starts on the master chart. This indication is required for cases when the slave chart cannot be scrolled to the specified date and time. For
example, if the timeframe of the master chart is set to M1, while the timeframe of a slave chart is MN, and the time of the master chart falls on
the current bar of the slave chart (see screenshot 2).

If the line obstructs the view, it can be hidden by selecting “No” in the “Show the line” parameter (see the “Corresponding
bar line” parameters block). 

Selecting slave charts

By default, the indicator selects all charts opened in the terminal as slave charts. However, it is also possible to configure the indicator
so that it selects only the charts with the symbol matching that of the master chart, or the ones with the timeframe matching that of the master
chart. This can be done using the “Synchronize the charts” parameter, which provides three synchronization options: “All”
(default), “By symbol” and “By timeframe”. If the “By timeframe” option is selected, then only the USDCHF M1 chart will be selected as slave
(see screenshot 3).

Accordingly, if the “By symbol” option is selected, then only the EURUSD M5 chart will be selected as slave (see screenshot 4).

Copying graphical objects

The utility also provides the ability to copy graphical objects. Thus, is a graphical object supported by the indicator is displayed on the
master chart, it will immediately appear on each of the slave charts (see screenshot 5). Deleting or changing the properties of an
object leads to similar changes on the slave charts.

Supports graphical objects: vertical line, horizontal line, trendline, trendline by angle, cycle lines, equidistant channel, standard
deviation channel, linear regression channel, Andrews’ pitchfork, Gann line, Gann fan, Gann Grid, Fibonacci retracement, Fibonacci
time zones, Fibonacci fan, Fibonacci arcs, Fibonacci channel, Fibonacci expansion, rectangle, triangle, ellipse, icons, arrows, text.

For each of the types of objects there is a parameter that allows or prohibits copying this type of object.

Buttons on the master chart

It is easy to find the master chart on the screenshots 1-5 by buttons located at the bottom right corner of the chart. If necessary, the display
of these buttons can be disabled by selecting “No” in the “Show the control buttons?” parameter.

If the buttons are displayed, pressing the “Master chart is ON” button will transfer its status to “Master chart is off”. From this moment on,
the movement of the master chart on the time scale will not lead to the automatic movement of the slave charts.

Pressing the “Objects copy is ON” button toggles its state to “Objects copy is off”, deleted the copies of graphical objects from the slave charts
and stops monitoring the updates of the graphical objects on the master chart.

Crosshair

If the parameter “Using crosshair” is set to “YES”, then the functionality of working with a crosshair becomes available. Display and hide
the crosshair possible by pressing the “Tab” key. If the synchronization of graphical objects is enabled, the crosshair will be displayed
on all slave charts. To fixing the crosshairs at any point click the left mouse button. A line appears with a hint containing such data
relative to the fixation point: the number of bars, the number of points, the current price. The next click with the left mouse button moves
the crosshair to the current point.
