The multiplier affects your winnings and losses and not the needed margin.

@developing-coder said in LaguerreRSI:

Am I missing something?

Yes, you are trying to use something without even having looked at literature for it.

The definition of the LaguerreRSI has no period. This was a contribution taken at the very beginnings and period was simply there.

open/current of an open order,

Sorry you are obviously not looking for what open orders have.

@vasco-laranjo said in Open Order's side as a Factor on the Strategy condition:

for instance on the below I would like to apply it only if "and current position is short (sell side)".

You are looking for the actual position. Use the size of the position (which is being tested as a boolean but has a sign and is used in several samples)

You have to copy the attributes.

Strategies don't need any kind of repopulation. As for the broker, you will have to add the orders without triggering spurious notifications which would be a kind of false positives given to the strategies

The resampler doesn't know anything about your extra lines and that's why the values aren't carried forward.

@dmitry-hits said in Save optimization results for plotting:

Is there an easy way to export those results for plotting, for example?

Not really. Plotting was meant to plot single-run results. You could always pickle the results, but that won't help with plotting
them.

@dmitry-hits said in Save optimization results for plotting:

but did not find how to extract the ending value of the broker for each set of parameters.

Save the result during the stop method of the strategy.

The code is unreadable ... pleas see the top of the forum.

This seems related to your usage of the CCXT fork, as per your other message:

• https://community.backtrader.com/topic/623/anyone-use-backtrader-to-do-live-trading-on-bitcoin-exchange/301

The fork will have to handle it.

Not being even a beginner in the usage of IPython

1. Anaconda has nothing to do with this. It's a distribution.

2. Jupyter is the graphical frontend and as such meant for plotting

3. IPython is focused on interactive Python, i.e.: it is a console.

Try plotting disabling the ipython automatic detection when calling plot
