Hi,
Could you help understand how to backtest intraday strategy?
For example, in the handle_data function I would like to open position with open price and close it with close price.
I do it this way:
order(context.security, 10, limit_price = data[context.security].open_price)
order(context.security, -10, limit_price = data[context.security].close_price) But I don't see this 2 transaction in the transactions.
Do you have example for this kind of backtesting?
Thanks.
Hi Denis,
In order to implement an intraday strategy, you will need to run your backtest in minute mode. If you would like to only order at market open and market close, you can use the schedule_function() to schedule each of these methods.
As an example:
def initialize(context):
schedule_function(
func=open_positions,
date_rule=date_rules.every_day(),
time_rule=time_rules.market_open(minutes=1),
half_days=True
)
schedule_function(
func=close_positions,
date_rule=date_rules.every_day(),
time_rule=time_rules.market_close(minutes=1),
half_days=True
) And then you can define the open_positions(context, data) and close_positions(context, data) methods to trade as you would like!
