Using 'complicated' formulas in Conditions
« on: 18 Feb 2013, 01:50 »
Hi all,

I am new to MFP and also to complicated looking formulae and wondered
if anyone could enlighten me as to what  "qualify_market_parent_id"
means ? It is shown in the 'Football Cash Generator.mft'  trigger.
Thanks to all those wise owls out there   :)

Hi
It is the name under which a list of matching selections is remembered.
You need to have an understanding of the Remember trigger action, and Remembered Selection’s Variables. See the relevant sections in the manual.

The Remember action remembers, or makes a list of all selections that match the conditions in the remember trigger.
These selections are remembered under a name, which could be anything (similar to the name of a user variable).
For example: Name: myselections
You can now access variables relating to the remembered selections: myselections_2_last_traded will return the last traded price of the second matching selection in the remembered list.

In the Remember action Name field you can put a trigger expression, which means you can use variables in the Name.   
In the example you are asking about : qualify_market_parent_id
<qualify>_ is any name
<market_parent_id> is the variable market_parent_id

So you are remembering selections that match the conditions of the remember trigger under the name qualify_market_parent_id
Please read the following disclaimer with regards to the information you may request and obtain on our forum. This specifically concerns trigger files and various instructions as to how to implement a strategy.
