Happy National Day. My understanding of cross-regional or cross-product arbitrage. Find correlations, related products or markets. Discovering some simple rules is much better than listening to the analysis of various masters. After all, your own wisdom can be used at any time.

The A-share market is rising. Domestic trading is not allowed during the National Day, but Hong Kong stocks can be used. Buy.

BTC is falling. The altcoins with a downward trend will be driven to accelerate the decline. Sell.

In the past, when studying the double moving average indicator, BTC may have a golden cross at 9 o'clock, and some have not yet, so find those that have not yet done so and go long. Of course, the trend structure of the K-line should be upward.

It's like going hunting. You stand in a ditch and a rabbit comes towards you and runs in your direction. There is no need to chase it, just shoot it directly.
