# `t`

```elixir
@type t() :: %Bourse.WS.Semantics.Ohlcv{
  cache_type: String.t() | nil,
  caches: %{required(String.t()) => map() | nil},
  closed_signal: String.t() | nil,
  timeframe_key: String.t() | nil,
  update_model: String.t()
}
```

# `apply`

```elixir
@spec apply(t(), String.t(), term()) :: {t(), map() | nil}
```
