4) FORMULA SYMBOLS.
In Tradesignal 9, formula symbols (formerly known as composite symbols) now behave as first-class instruments, in that they may be freely inserted, replaced, deleted, traded in the same way as exchange provided symbols*. This new behaviour also overcomes the two major limitations of the older mechanism: You can mix formula and non-formula symbols in a watchlist and update linked charts. It is also possible to apply templates to a chart containing a formula symbol.
Please note: This new behaviour will only apply when a formula symbol is newly added to a workspace. Items in existing saved workspaces (created prior to version 9.1) cannot be migrated. Formula symbols created prior to this version will appear differently in a symbol list (greyed out), and will continue to operate in the old way if used.
*Formula symbols will only support a subset of Equilla commands, specifically those that do not involve sharing (globals) or persisting data, extension interfaces and non-price output mechanisms (print, alert, etc.). The formula editor will generate an error if non-supported commands are used.
4.1 Formula Symbol Wizard – Creating Formula Symbols without Coding.
The editor for creating and editing formula symbols has been enhanced to support formula symbol templates. A drop-down menu at the top of the dialog allows you to pick from pre-existing symbol templates you would like to create a symbol from.
The following formula symbol templates have been added as standard:
- Spread Diff Template
- Spread Diff Bars Template
- Spread Quot Template
- Spread Quot Bars Template
- Spark Spread Template
- Clean Spark Spread Template
- Dark Spread Template
- Clean Dark Spread Template
- Climate Spread Template
- Crack 3-2-1 Spread Template
- Crush 1-1-1 Spread Template
- Custom Session Symbol Template
And here`s how to create a new formula symbol using a template: First, select one of your symbol lists and click on “New Symbol” and then “New Formula Symbol”. Let`s say you would like to create a Spark Spread. Using Tradesignal 9, you can pick the corresponding template to create your formula symbol with no need to program.
