Thanks!

I tend to change my csv format quite often, so is there a way to automatically detect all the extra columns in the csv and add them as lines?
Accessing 'self.lines' in the derived class' init method does not seem to be the way to do it.

Thanks!

Hello,

I have a csv with additional custom columns, other than the usual open, low, high, close, volume, openinterest. I would like to load this csv as a data feed, such that I have the additional columns as additional lines that I can use in the 'next()' function.

Is there a way to do that? I failed to do so using the 'GenericCSVData' class.

Thanks!

Works like a charm, thanks for the detailed answer!

Thanks.
I read the link you attached for the documentation.
Note that the size parameter in buy() is interpreted as face value even I set a percentage commission:

cerebro.broker.setcommission(commission=0.005, commtype=bt.comminfo.CommInfoBase.COMM_PERC)
self.buy(data=self.data0, size=1)

Then in notify_order:
order.executed.price
1.8768
order.executed.comm
0.009384 # This is 0.5% of 1.8768, makes sense so far
cerebro.broker.getvalue(self.datas)
1.0 # size parameter in buy() was interpreted as face value, not as amount of shares t buy.

But my question is the following:
How do I set the commission to be in in fixed monetary units, but still have the 'size' parameter in 'buy()' interpreted as the amount of shares to buy?

Hi,

When I use:
cerebro.broker.setcommission(commission=0.005)

and place a buy order:
self.buy(data=self.data0, size=1)

I see in 'notify_order' when the order status is order.completed:
order.executed.price = 1.8768
cerebro.broker.getvalue(self.datas) = 1.9732
self.data0[0] = 1.9732

which indicates that 1 unit of the stock was bought.
However, when I set
cerebro.broker.setcommission(commission=0.005, commtype=bt.comminfo.CommInfoBase.COMM_FIXED)
and use the same buy order I get when the order is completed

order.executed.price = 1.8768
cerebro.broker.getvalue(self.datas) = 1.0
self.data0[0] = 1.9732

which indicates that the order was places to buy as many units as possible for 1 monetary unit.

Is this a bug or a feature?
How can I set a fixed commision in monetary units and still place buy orders where the size parameter indicates units of the stock to buy?

Thanks!

Thanks!

I managed to overcome this with the chrome extension "High Contrast":

In my firefox it looks the same as in my chrome. Weird!

Hi,

Platform is really awesome, just one problem:
The online docs looks like that:

With my chrome and Ubuntu 14.04. It's very hard to read with these colors. Is this normal? Any hack to overcome this?

Thanks!
