@pomnl I've had success using this strategy with bulky data.

@ab_trader 's answer here is good.

@ab_trader Not sure if this is an issue since I did this a long time ago.... But when i was putting in stocks for an asx200 analysis going back a long time, some of the stocks didn't have data either at the beginning or the end. I had to at the time use pandas to fill in the beginning and ends with zeros before passing this into backtrader. Again, I was pretty green with backtrader then so not sure if this practice is necessary or not.

@vladisld That's what I do... :)

You can set up your variable in notify_order at the end. When the order has traded, set your variable to four hours out, then check that variable at the beginning of next.

To get a line for ema as you ask...

self.myema = bt.ind.EMA((self.datas[0].high / self.datas[0].low) /2 )

When printing use the format

:.4f

To add to @ab_trader great answer, you can get the order execution price in notifiy_order using:

order.executed.price

To clarify, you have a return if current time is less than self.no_trade_time.

You can simply have a variable (self.no_trade_time) or something like that, place it at the beginning of next and if the time is before that time, no trades. Every time you stop, set the variable 4 hours out.

What is the nature of the data you are using?

@coddy said in how to upload several stocks data in backtrader?:

class SmaCross(bt.SignalStrategy):

Try changing this to:

class SmaCross(bt.Strategy):

Does this means you can't plot with backtrader on colab? That is a pity.

Also have a look at this plotting library. Might solve your problem.

No it means I haven't used Colab with backtrader. I've seen discussions online regarding this issue, it might have been solved somewhere.

Have a look here. bt.DivByZero

There's a current thread on this topic here

Have a look at my post here.

Did you try this?

The indicator will try to automatically plo to the non-resampled data. To disable this behavior use the following during construction:

_autoplot=False

ut just another trivial point that I missed is that, do restart your kernel

Not so trivial me thinks... :)

Can you explain that line of code? When would they not be different?Thanks!

One minute date, checking for new date at the beginning of the day. :)
