@annuit 不错不错！代码简洁，思路清析。受教了！

File "/tmp/strategy/user_code.py", line 3 g.security='000001.XSHE' ^ SyntaxError: invalid synta 这是怎么了

小于10%是不是-0.1

@13269028413 10%是0.1吧？

@prince flower 我也想问，一样错误，可能是更新了

``` def initialize(context): run_daily(period,time='every_bar') g.security = '000001.XSHE' def period(context): date=context.current_dt.strftime("%Y-%m-%d") if date=='2018-03-01': order(g.security,100) elif date == '2018-03-21': print(f"======={order(g.security,100)}") ```

@风树 这是Python语法错误，因为Python对空格敏感，可能是g.security前面非空格不对，空格数为2，或者使用tab键替代。

``` def initialize(context): run_daily(period,time='every_bar') g.security = '000002.XSHE' def period(context): b = format(context.current_dt) if b == "2018-08-01 09:30:00": order(g.security, 100) print('买入100股') if b == "2018-08-21 09:30:00": order(g.security, -100) print('卖出100股') ```
