Historic Search

Historic Search is a feature in FX Sales that enables sales traders to search trading history beyond the typical 30-day limit imposed by standard FX Sales blotters.

Overview

Historic Search is a dedicated search interface to a back end data source, typically a database, that stores trading history beyond the typical 30 days' of activity available in standard FX Sales blotters.

The Historic Search user interface comprises a query builder and a results blotter. The query builder allows users to easily build complex queries from a selection of search criteria. The search results blotter does not impose any constraints except for those specified by the search criteria.

The Historic Search back end is handled by the FX Integration API, which provides developers with extension points for implementing the configuration of the query builder’s search criteria (SearchConfig) and the execution of a search query (SearchBlotterListener).

Requirements

Historic Search has the following requirements:

Historic Search user interface

The Historic Search feature provides a rich user interface for building search queries:

  • Available search criteria can be configured on a global or per user basis.

  • Multiple search field types:

    • Text

    • Number range

    • Date range

  • Users can refine search results using FX Sale’s blotter sorting and filtering options

Backend integration

Historic Search depends on an implementation of a SearchBlotterListener that integrates with a back end source of historical trades, usually a database.

The FX Sales' user interface generates a search expression that adheres to the following syntax:

image/svg+xml ( field == != >= <= > < value ) & |

Each search comprises a series of fields, values, boolean operators, comparators, and optional parenthesis.

Boolean operators (in order of precedence)

&

Logical AND

|

Logical OR

Comparators
Comparators Description

==

Equals

!=

Not equals

>=

Greater than or equal to

<=

Less than or equal to

>

Greater than

<

Less than

The search expression is parsed by the FX Integration API and passed to the SearchBlotterListener.searchChannelOpened method as a parse tree of SearchExpression objects. Developers can use the parse tree to build a SQL query, API query, or filter.
