Mechanic of next(self) function. Explain me please by experience

[SPECULARI FUND]

Last 2 days I am testing live data feed. I noticed, that first resample timeframe is major for "next(self):" function. right?
So, if all logic calculates inside of this "loop" it will calculates at the same "speed" as your major timeframe, right?
My major resample timeframe is 1 minute, and when I receive signal my order create and it executes after 1 minute...or I am wrong? On backtesting I didn't understant this moment untill try live data, so looking for asnwer from experienced guys. Thx!

If you place an order, it will be execute on the next bar by open price. If you send order to broker, and this order is market - it will be execute from order book(from takers).

Sorry, *if you send order to broker in live mode

@Yaroslav-Horyslavets thx for reply. Looks like I can't understand it because I test it without broker platfrom (only live feed) and my logs show after each "next()".

next() is called on every bar of all data feeds (resampled or not resampled).

@ab_trader how to check what minimal timeframe data feed can send?

[ab_trader]

have the data feeds names related to the time frames. print data feed self.datas[x]._name name on each next() using log function. this will also give the date and time.

@ab_trader all my questions about orders event handling. But I understand that if I had broker terminal I wasn't confused with logs output and next(). Anyway, thank you for replies!

In this case I am not sure what is your confusion. Live broker or simulation broker - approach is the same.
