tensortrade.feed.api.float.accumulators module

class tensortrade.feed.api.float.accumulators.CumMax(*args, **kwargs)

Bases: tensortrade.feed.core.base.Stream

A stream operator that creates a cumulative maximum of values.

Parameters

skip_na (bool, default True) – Exclude NA/null values. If a value is NA, the result will be NA.

forward() → float

Generates the next value from the underlying data streams.

Returns

T – The next value in the stream.

has_next() → bool

Checks if there is another value.

Returns

bool – If there is another value or not.

class tensortrade.feed.api.float.accumulators.CumMin(*args, **kwargs)

Bases: tensortrade.feed.core.base.Stream

A stream operator that creates a cumulative minimum of values.

Parameters

tensortrade.feed.api.float.accumulators.cummax(s: tensortrade.feed.core.base.Stream[float], skipna: bool = True) → tensortrade.feed.core.base.Stream[float]

Computes the cumulative maximum of a stream.

Parameters

• s (Stream[float]) – A float stream.

• skipna (bool, default True) – Exclude NA/null values. If a value is NA, the result will be NA.

Returns

Stream[float] – The cumulative maximum stream of s.

tensortrade.feed.api.float.accumulators.cummin(s: tensortrade.feed.core.base.Stream[float], skipna: bool = True) → tensortrade.feed.core.base.Stream[float]

Computes the cumulative minimum of a stream.

Parameters

• s (Stream[float]) – A float stream.

• skipna (bool, default True) – Exclude NA/null values. If a value is NA, the result will be NA.

Returns

Stream[float] – The cumulative minimum stream of s.

tensortrade.feed.api.float.accumulators.cumprod(s: tensortrade.feed.core.base.Stream[float]) → tensortrade.feed.core.base.Stream[float]

Computes the cumulative product of a stream.

Parameters

s (Stream[float]) – A float stream.

Returns

Stream[float] – The cumulative product stream of s.

tensortrade.feed.api.float.accumulators.cumsum(s: tensortrade.feed.core.base.Stream[float]) → tensortrade.feed.core.base.Stream[float]

Computes the cumulative sum of a stream.

Parameters

s (Stream[float]) – A float stream.

Returns

Stream[float] – The cumulative sum stream of s.
