Monday's Move in Bitcoin was a Huge Outlier

The weekend move in Bitcoin extended into Monday's trading and Bitcoin ended up rising 25%. You can see how much of an outlier that was on my daily trading return vs. volatility graph:

Since then, Bitcoin has gone into another consolidation range. This morning it looked like we might get stopped out of the long trade at the open, but the market bounced and we are still long from 5285.

P.S. 12:55pm

We just closed the long position and went short at 7715. Profit on the trade was USD 12.1k Of course, all this was done automatically via stop orders. 20 minutes later the short is up USD 5k. This is crazy price action.

Bitcoin Going Completely Nuts Over the Weekend

I've noticed that in recent days Bitcoin has gone up starting at around 6pm US Eastern time when all stock markets in the World apart from New Zealand are closed. Of course, this is the afternoon and evening on the US West Coast. So, I figured that it was driven by retail investors in the U.S. Now this weekend, that trend has continued in dramatic fashion:

Bitcoin is up almost $700 on Friday's close. Luckily, I am long Bitcoin futures. It certainly makes me wary of ever being short Bitcoin over the weekend. Bitcoin has now popped up to be my 22nd best investment in dollar terms ever - I've been investing since 1996... Just about to overtake Pendal Property Investments. Anyway, anything could happen by 10am Monday Eastern Australia time when the futures market re-opens...

P.S.
Obvious solution to going short over the weekend is to have an account with a cash Bitcoin exchange that is open over the weekend and buy Bitcoin if the stop loss level is reached. What such exchanges allow stop orders?

P.P.S.
Bitcoin now up $1000 since Friday. If this persists till Monday it will be the biggest daily move in percentage terms in my dataset, possibly since the futures market open at the end of 2017. Plus 500 allows CFD trading 24/7. There are huge buy-sell spreads, so this would only be used as insurance. You can place conditional orders, such as buy only when the price reaches a certain level.

P.P.P.S.
I tried the demo platforms at Plus500 and eToro. eToro appears to be very limited and geared to novice traders. There were strong restrictions on the levels of orders that could be placed. So, Plus 500 seems to be the only real option that offers Bitcoin CFD trading 24/7.

More Asymmetry

A couple of days ago I posted about the asymmetry of market returns capture by the target portfolio. The portfolio captured less than 100% of the upside in the markets but almost none of the downside. The chart below, inspired by a recent paper from AQR, shows the Bitcoin trading model's daily returns compared to the absolute percentage change in the price of Bitcoin futures for that day:

The rising diagonal line are all the days when the model was properly aligned with market direction. The descending diagonal line are all the days where it was incorrectly aligned with market direction. The remaining cloud of points is where the model changed direction. Some of those days were winners and some very bad losers when the model ended up incorrectly with the market in both directions that day. For example, it was stopped out of a long position and entered a short and then the market rose for the rest of the day...

The fitted quadratic curve shows that for low absolute price changes up or down in the price of Bitcoin, the model tends to lose money. This is because of "whipsaw". There is a strong asymmetry in the response for large moves and so the fitted curve shows that the model captures increasingly more of the return the larger the move.

The results do conform to AQR's argument that returns to trend-following have been poor recently because markets haven't been moving enough.
