$ERA long and short, long position 4000, short position 8000 profit, no afterthought.

Long holder selling pressure, after the surge the order book is filled with 3000x10 small short positions.

After finishing the shorts, I did a long position, upbit didn't go up, I thought it was supposed to open but didn't.

So in Korea at 12:30, and can only use the ETH chain, the price difference between the two chains is significant, possible arbitrage, long and short in the same position.

Overall fee rate, sell to Koreans later, eat the fee.

Thinking time is 2 minutes, real trading position, see the process in the picture..
