Custom error types for the bts library.

Variants

CandleDataEmpty

The candle data provided is empty.

Backtesting requires at least one candle to execute.

CandleNotFound

The requested candle was not found in the dataset.

InvalidFactor

The Aggregator factor is invalid.

MissingField(&'static str)

A required field is missing.

InvalidPriceOrder(f64, f64, f64, f64)

Prices are not in valid order (open ≤ low ≤ high ≤ close).

NegativeVolume(f64)

Volume cannot be negative.

InvalideTimes(DateTime<Utc>, DateTime<Utc>)

Open time and close time are not in valid order (open time < close time).

NegZeroBalance(f64)

The initial or current balance is not positive.

Arguments

• 0 - The invalid balance value.

InsufficientFunds(f64, f64)

The wallet does not have enough funds to place the order.

Arguments

• 0 - The required amount.
• 1 - The available amount.

NegFreeBalance(f64, f64)

The free balance is negative.

Arguments

• 0 - The current balance.
• 1 - The locked funds.

NegZeroFees

The fees are negative.

UnlockBalance(f64, f64)

The locked funds are insufficient for the requested amount.

Arguments

• 0 - The currently locked funds.
• 1 - The requested amount to unlock.

OrderNotFound

The requested order was not found.

RemoveOrder

Failed to remove an order.

PositionNotFound

The requested position was not found.

RemovePosition

Failed to remove a position.

ExitPrice(f64)

The exit price is invalid.

Msg(String)

A generic error with a custom message.

Arguments

• 0 - The error message.

NegTakeProfitAndStopLoss

Take profit or stop loss values must be positive.

NegZeroTrailingStop

Trailing stop values must be positive.

MismatchedOrderType

The order type is not compatible with the operation.

Use market or limit orders to open a position, and take profit, stop loss, or trailing stop to close a position.

Io(Error)

An I/O error occurred.

Arguments

• 0 - The underlying I/O error.

MutexPoisoned(String)

A mutex was poisoned.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl Serialize for Error

Available on crate feature serde only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
