User Notes:
This FFCal Panel indicator is coded to run on MT4 Build 600+. It places a panel on the chart in
which are displayed up to four news releases listed on the Forex Factory Calendar. Details are
provided below.
FFCAL PANEL CONTENTS -
The time, title and ranking (by color) of the releases are shown.
The time of a releases is important because the market frequently holds price moves until after
important releases come out. Also, Market Makers can prepare in advance for these moves. The
Market Makers and banks do know the essence of news and releases in advance, and there is no
regulation against insider trading in the forex market. Banks can place orders in advance of
releases and Market Makers can use the intervening time to move prices to fill those orders,
saving the move that will make profits on the orders until the time of the releases.
The title of the release, and it's ranking by color, is important because the variety of low
impact releases frequently have no effect on price, whereas the variety of high impact releases
can trigger a big price move, or can cause Market Makers to start moving prices days in advance,
in preparations for big moves to be made in conjunction with those releases.
Of the three impact level events (High, Medium, Low) and Bank Holidays, you have the option to not
show all but the High Impact events. The Previous/Forecast data (available on the Forex Factory
Calendar) is not displayed because prices can go either way regardless of specifics released. it
is the timing of news that is important, as a market volatility event.
THE PRIORITIZATION OF EVENTS -
Prioritization of events is fully automated and two more event labels are added to help avoid
surprises. When two or more events occur simultaneously, only one event of the highest impact
displays unless there are multiple high impact events. In that case the multple high impact
events are displayed. When 2nd, 3rd or 4th events are not scheduled, text noting that appears.
A current day Bank Holiday will remain displayed in the first label until the Bank Holiday is
over. You can show events for any pair on any chart. For example, you can show a CNY (China)
event on a AUDUSD chart. A new option is added allowing you to ignore the chart pair and
select what currencies you want to show news for, so that you do not have to display the news
for the chart pair.
THE ALERT -
You can specify to be alerted "x" minutes ahead of the scheduled release of Event #1. When
that time arrives, an alert will sound/appear on the chart. If during the same minute, while
the relase time and the alert time are of the same minute, if you change chart time framse the
alert will retrigger on the selected new chart time frame. After that minute passes, there will
be no retrigger of the set alert under any circumstances. Enter your "Broker_Name_In_Alert" to
avoid confusion if simultaneously using multiple platforms.
When "Alert_Minutes_Before_Event_1" is set at "0" the Alert is not set to function. If any
other number appears, the Alert is set to function. When the Alert is set to function....
* If the minutes input is less than the time to the release of Event #1, the Alert is set
to trigger and "Alert Pending" appears in the FFCal title.
* If the minutes input equals the time to the release, the Alert triggers and "Alert Received"
appears in the FFCal title.
* If the minutes input now exceeds the time to the release, the release is already one or
more minutes into the past and "Alert Completed" appears in the FFCal title. When this is
the case, open the External Inputs and reset the input to "0" to turn off the Alert.
THE TFs FOR DISPLAY OF FFCAL -
You can select a range of TFs for the display of this indicator, so it automatically will not
display on a chart TF outside that range. The indicator can be turned on/off without having
to remove it from the chart, thereby preserving your chart settings.
