Member Data Documentation

UNDEFINED

DXFCPP_BEGIN_NAMESPACE const Direction Direction::UNDEFINED {0, "UNDEFINED"}

static

Direction is undefined, unknown or inapplicable.

It includes cases with undefined price value or when direction computation was not performed.

ZERO

const Direction Direction::ZERO {3, "ZERO"}

static

Current price is equal to the only known price value suitable for price direction computation.

Unlike UNDEFINED the ZERO direction implies that current price is defined and direction computation was duly performed but has failed to detect any upward or downward price movement. It is also reported for cases when price sequence was broken and direction computation was restarted anew.
