leverage doesn't affect returns in backtesting

I'm a bit confused with the leverage,
I ran my strategy twice, first time setting leverage 400, second time leverage 800, here's how I set the leverage:
cerebro.broker.setcommission(commission=0.0, leverage=400)
then
pprint
ed thebt.analyzers.TradeAnalyzer
with:print('TradeAnalyzer :') stats[0].analyzers.TradeAnalyzer.pprint()
In both cases I get a bunch of stats about my analyzer, but what is strange is that the analysis I get is absolutely the same, numbers are an exact match for both leverages.
Also my broker cash and broker value are the same.

If you have same trade stats for both cases, than (as a guess) you didn't increase position size to use that increased
leverage
.

Right.

You are confusing
leverage
withmultiplier
(which is used for example with Futures).
leverage
gives you more buying potential. But it is a potential and the decision as to how much of that potential to use is yours 
multiplier
: affects directly the returns. Unfortunately assets in reallife have a fixed multiplier and you cannot choose it.


thanks, now it makes more sense.
