Module study 

TradingView study and fundamental data retrieval.

Provides a clean, high-level API modeled after crate::historical::HistoricalClient for fetching TradingView indicator studies (both built-in and Pine Script studies) over WebSocket.

Architecture

StudyClient::retrieve(request)
  ├── StudyRequest       (symbol/exchange, study config, interval, bar count, timeout)
  ├── StudyState         (accumulates points keyed by study ID, tracks completion)
  ├── StudyDataHandler   (inspects timescale_update / du for study points)
  └── returns StudyResult (symbol info, sorted/deduplicated points, elapsed duration)

Example

use tradingview::Interval;
use tradingview::chart::study::StudyConfiguration;
use tradingview::study::{StudyClient, StudyRequest};
use tradingview::models::pine_indicator::{PineIndicator, ScriptType};
use tradingview::DataServer;

let client = StudyClient::new("unauthorized_user_token", DataServer::Data);

let indicator = PineIndicator::build()
    .fetch("STD;Fund_total_revenue_fy", "69.0", ScriptType::IntervalScript)
    .await?;

let request = StudyRequest::builder()
    .symbol("AAPL")
    .exchange("NASDAQ")
    .interval(Interval::OneDay)
    .base_bar_count(100)
    .study(StudyConfiguration::Pine(Box::new(indicator)))
    .build();

let result = client.retrieve(request).await?;
println!("received {} study points for {}", result.len(), result.symbol_info.name);
