Types

type AggsClient 

type AggsClient struct {
	client.Client

AggsClient defines a REST client for the Polygon aggs API.

func (*AggsClient) GetAggs deprecated 

func (ac *AggsClient) GetAggs(ctx context.Context, params *models.GetAggsParams, opts ...models.RequestOption) (*models.GetAggsResponse, error)

GetAggs retrieves aggregate bars for a specified ticker over a given date range in custom time window sizes.
