# List

This endpoint displays trade data based on filters set in the arguments.

This is done by dividing a given time range into segments and aggregating statistics, for a given asset pair (base, counter) over each of these segments.

The duration of the segments is specified with the `resolution` parameter. The start and end of the time range are given by `startTime` and `endTime` respectively, which are both rounded to the nearest multiple of `resolution` since epoch.

The individual segments are also aligned with multiples of `resolution` since epoch. If you want to change this alignment, the segments can be `offset` by specifying the offset parameter.

 \- ARGUMENT - 

* start\_time `long`

  The lower time boundary represented as milliseconds since epoch.
* end\_time `long`

  The upper time boundary represented as milliseconds since epoch.
* resolution `long`

  The segment duration represented as milliseconds. Supported values are 1 minute (60000), 5 minutes (300000), 15 minutes (900000), 1 hour (3600000), 1 day (86400000) and 1 week (604800000).
* offset `long`

  Segments can be offset using this parameter. Expressed in milliseconds. Can only be used if the resolution is greater than 1 hour. Value must be in whole hours, less than the provided resolution, and less than 24 hours.
* base\_asset\_type `required`

  The type for the base asset. Either `native`, `credit_alphanum4`, or `credit_alphanum12`.
* base\_asset\_issuer `optional`

  The Stellar address of the base asset’s issuer. Required if the `base_asset_type` is not `native`.
* base\_asset\_code `optional`

  The code for the base asset. Required if the `base_asset_type` is not `native`.
* counter\_asset\_type `required`

  The type for the counter asset. Either `native`, `credit_alphanum4`, or `credit_alphanum12`.
* counter\_asset\_issuer `optional`

  The Stellar address of the counter asset’s issuer. Required if the `counter_asset_type` is not `native`.
* counter\_asset\_code `optional`

  The code for the counter asset. Required if the `counter_asset_type` is not `native`.
* order `optional`

  A designation of the order in which records should appear. Options include `asc`(ascending) or `desc` (descending). If this argument isn’t set, it defaults to `asc`.
* limit `optional`

  The total number of records returned. The limit can range from 1 to 200 - an upper limit that is hardcoded in Horizon for performance reasons. If this argument isn’t designated, it defaults to 10.
