Coasyn Session Anchor
Coasyn Session Anchor
Coasyn Session Anchor is an intraday session-reference tool for marking important FX trading-session events directly on the chart.
The indicator can track:
Tokyo Open
Tokyo Close
Europe Open
London Open
New York Open
New York Close
Each enabled event can create:
a vertical timing marker showing when the session event occurred
a horizontal price anchor extending from that event
an optional label identifying the session
The indicator does not generate trade signals, determine market direction, or execute orders.
Its purpose is to provide consistent session timing and price-reference levels.
How to use it
Open the indicator settings and first choose your Anchor Timezone.
The default is:
Etc/UTC
All session times entered in the indicator are interpreted using this timezone.
For each session event, you can:
Enable or disable the event.
Enter the event time using HH:MM format.
For example:
00:00
07:00
08:00
13:30
Session times
The default configuration is:
Tokyo Open — 00:00
Tokyo Close — 09:00
Europe Open — 07:00
London Open — 08:00
New York Open — 13:30
New York Close — 21:00
These times are fully editable.
If your preferred session definition, broker convention, daylight-saving adjustment, or operating timezone is different, change the values in the settings.
Horizontal anchor price
The Horizontal Anchor Price setting determines which price is used when a session event occurs.
Event Open
Uses the chart bar's opening price when the session anchor is detected.
Event Close
Uses the chart bar's closing price.
The resulting level extends to the right as a reference for later price interaction.
Vertical session markers
Enable:
Show Vertical Session Timing Lines
to draw a vertical line at each enabled session event.
This provides a visual reference for when major trading sessions begin or end.
Horizontal session levels
Enable:
Show Horizontal Anchor Levels
to extend the selected event price across the chart.
These levels can be used to observe how price behaves relative to prior session participation points.
The indicator does not assign bullish or bearish meaning to those levels.
Labels
Enable:
Show Anchor Labels
to identify each session directly on the chart.
Labels include:
TOKYO OPEN
TOKYO CLOSE
EUROPE OPEN
LONDON OPEN
NY OPEN
NY CLOSE
Historical anchors
By default, Keep Historical Anchors is disabled.
When disabled, each session event keeps only its most recent anchor.
For example, when the next London Open occurs, the previous London Open anchor is removed and replaced with the new one.
Enable Keep Historical Anchors if you want previous session anchors to remain visible.
Be aware that keeping large amounts of historical session data can create substantially more chart objects.
Display controls
The indicator allows you to configure:
session colors
line width
horizontal levels
vertical timing markers
labels
historical anchors
Each major session can use its own color so different session events remain easy to distinguish.
Example workflow
A trader operating during the London and New York sessions might enable:
Europe Open
London Open
New York Open
while disabling session events they do not use.
The chart will then maintain timing and price anchors for those specific events.
This makes it easier to observe whether price is trading:
above or below a session-opening reference
back through a prior session level
around the transition between trading sessions
The interpretation remains entirely with the trader.
Timeframe note
Coasyn Session Anchor is designed primarily for intraday charts.
The precision of an anchor depends on the chart timeframe.
On lower intraday timeframes, the bar containing the configured session time will generally provide a more precise representation of that event.
On larger chart intervals, one candle may span multiple session events, so the event price should be treated as a broader reference rather than an exact tick-level session price.
Important
Coasyn Session Anchor is an informational charting tool only.
It does not provide:
buy or sell signals
trade entries
targets
stop placement
position sizing
automated execution
directional recommendations
It provides time and price anchors around the session events selected by the user.
