Drawdowns module - server — mod_drawdowns

Analyses the falls of the coin selected in the Timeseries tab from its all-time high with drawdown_analysis(), and shows them in words, as a chart and as a table. The CSV file, named like bitcoin-btc-drawdowns-2026-11-06.csv, holds drawdown_csv(): a row per fall of the chosen size.

Usage

mod_drawdowns_server(id, history, dark_mode)

Arguments

id: Character. Module namespace id, must match the id used in mod_drawdowns_ui().
history: Reactive returning the price history of the selected coin, from mod_timeseries_server().
dark_mode: Reactive returning "light" or "dark", the mode of the app.

Value

None. Called for its side effect of registering the module server.

if (FALSE) { # \dontrun{

  dark_mode <- reactive(input$dark_mode)
  history <- mod_timeseries_server("timeseries", coins, dark_mode)
  mod_drawdowns_server("drawdowns", history, dark_mode)
