@backtrader as a workaround could I import the same data twice and give it two different names?

@backtrader Thank you for the feedback. So the closest I could get is to setup two instruments:

• Inst 1: BTCUSD (no leverage)
• Inst 2: BTCUSD (leverage 3x)

And use 70% of the cash to buy inst 1 and 30% on inst 2?

I would like to test a strategy that trades bitcoin with leveraged and unleveraged positions.
The strategy would run on bitfinex based on trend signal:

Long signal:

• 100% of the USD is used to buy BTC with no leverage
• 30% of the bought BTC is used to open a margin long BTCUSD position with 3x leverage and 10% stop loss

Short signal:

• 100% of collateral is in USD
• 30% of the USD collateral is used to open a margin short position with 3x leverage and 10% stop loss

I have hard time to figure how to handle the long scenario. I could create two commissions with leverage=1 and leverage=2 on two instruments based on the same BTCUSD price.

But how can I tell the broker to use the bought BTC (instrument 1) as a collateral for the leverage position (instrument 2)?

I'm a bit confused about this point.

Just getting started on backtrader and I'm loving in it. I have a 4k display and I would double the matplotlibe resolution for a "retina" display. How can I do that? Thank you
