setting min period inside the strategy

siavash

Hello,
How can I set the first start candle inside the strategy. I found that this is done by setminperiod(minperiod) method. But I don't know how to set that inside a strategy.

@siavash minperiod is set automatically (usually) as soon as all data has non-NaN values. If you need to define the first bar of your backtest, then just check the date/time of the bars in the next(). If it is higher then your start date, then process your rules.

I want to use for example 10 first candles inside the next method and after that sending order. I know that I can check date time inside the next method but it is so time consuming.

Both things have nothing to do with each other. If you want to skip 10 candles in next, check the length of the strategy itself.

You are probably in the wrong business if you consider than programming something to make money automatically for you is time consuming.

I didn't understand your answer. What is time cosuming?????!!!! I mean that is there better way to set min period rather than using date time.

You said that it is time consuming.

@backtrader
How can I skip. I dont know how?
I want to record 10 candles data and then send an order and save corresponding result in a text file. Also do this for remaining data. Could you please write code for help?🙏

if len(self) > (self.len_self_first_time_next_was_called + 10):
   # do something

Again: if things consider things to be time consuming and you can't write that simple code, you have to reconsider if you want to be in algotrading.
