I don’t know if I can really advise this, so I can only share my personal experience. I didn’t decrease the lot size. Risks increased, but so did the profits. This is a great time to trade actively intraday. It only happens once in a decade or so and doesn’t last long. The drawdowns remain about same, but the profits… mmm. Yummy! And it’s very motivating! I spend a lot of time investigating charts now, looking for new strategies, thinking about how to optimize the current ones. And it pays.
