500:1 leverage on short dated twitter calls before the musk news. it needs to be one trade because trading in and out several times in a day isn't possible due to clearing new proceeds.
You can't control profits only risk. Starting a thread like this that focuses on high leverage with a faulty assumption of catching all a move comes across like a red herring. Without identifying the instrument and it's ATR, there's no basis in the calculation. At 500:1, looks like a forex market which would imply a 1% daily average. I don't trade forex so I really wouldn't know.
Theoretically this is infinite%. Hard limit would be the market value of global assets and the economic value of their derivatives.
It's fine to use high leverage trading instruments as long as your trade is sized properly. If your risking >4-5% of your capital on trades your on a knifes edge, at >15% it's suicide. Fx has a lot of back-filling & whipsaws - the more leverage you use, the smaller a counter move can be to get you auto-liquidated with a margin call.
