exchange.SetMaxBarLen

Set the maximum length of the K-line (candlestick chart).

    
    
    
exchange.SetMaxBarLen(len)

Examples

Limit K-lines to at most 50 bars, then fetch them and print the count.

    javascript
    
    
function main() {
    exchange.SetMaxBarLen(50)
    var records = exchange.GetRecords()
    if (!records) return
    Log(records.length)
    // Output: an integer no greater than 50
}

    python
    
    
def main():
    exchange.SetMaxBarLen(50)
    records = exchange.GetRecords()
    if not records:
        return
    Log(len(records))
    # Output: an integer no greater than 50

    rust
    
    
fn main() {
    exchange.SetMaxBarLen(50);
    let Ok(records) = exchange.GetRecords(None, None, None) else { return };
    Log!(records.len());
    // Output: an integer no greater than 50
}

Remarks

The exchange.SetMaxBarLen() function affects the following two aspects when a cryptocurrency strategy is running:

• It affects the number of K-line bars (Bar) obtained on the first call.

• It affects the upper limit on the number of K-line bars (Bar).
