Struct DataRequirements 

pub struct DataRequirements {
    pub needs_real_volume: bool,
    pub needs_trade_direction: bool,
    pub session_sensitive: bool,
    pub roll_sensitive: bool,
    pub adjustment_sensitive: bool,
    pub needs_liquidity_depth: bool,
}

What an indicator’s calculation needs from the bar series it runs over, beyond plain OHLC prices. All-false (the Default) is the right value for pure price indicators — the effort of declaring requirements is only spent on the indicators where it matters.

Fields

needs_real_volume: bool

Needs real traded turnover, not tick/update count (e.g. volume profile, VWAP).

needs_trade_direction: bool

Needs classified individual trades (buy/sell direction), not just aggregate volume.

session_sensitive: bool

Result depends on where the session is cut (anchors, session extremes).

roll_sensitive: bool

Result depends on contract continuity (rolls mix liquidity pools / shift historical levels).

adjustment_sensitive: bool

Result depends on historical price levels matching what was actually traded (broken by split/dividend adjustment).

needs_liquidity_depth: bool

Needs market-depth information beyond what a thin series can provide.
