我有这个烧瓶应用程序路线：

@app.route('/generatecleanbudgetfile', methods=['GET', 'POST'])
def clean_budget():
    file = request.files.get('data_file')
    app.logger.info('Budget Formatting request has started')
    try:
        if request.method == 'POST':
            file = request.files.get('data_file')
            file.seek(0)
            buffer = budget_cleaner(file)
            buffer.seek(0)
            app.logger.info('Conversion Complete')
            return send_file(
            buffer,
            as_attachment=True,
            attachment_filename=f'stripped_budget_{dt.today().strftime("%m.%d.%Y")}.xlsx',
            mimetype='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
            )
    except:
        app.logger.error(f"Budget formatting failed on {file}")
        return render_template('error_type.html', title='Unable to process uploaded budget')  

我的HTML：

{% extends "base.html" %}
{% block head %}
{% endblock %}
{% block content %}
<div id="vo_budget_file_settings">
    {# <a href="/generatecleanbudgetfile" class="btn btn-primary">Upload Final CRO Budget File</a> #}
    <p id="uploadPara">Please upload …

我似乎无法弄清楚从交易进入的特定时间间隔退出交易的语法。任何帮助将不胜感激。

if (crossover(delta, 0))
    strategy.entry("Long", strategy.long, comment="Long")
    strategy.exit("Exit", "Long", when = 15)

上面的代码我想exit在15天后建立多头头寸。但这似乎不起作用。
