I use Binance.com the problem always starts when I trade pair trade. for example for today as I only traded the LTC - USDT pair no problem, everything is working perfectly, but if I trade the BTC - USDT pair in the trade history will not appear the LTC - USDT  pair, it will look like I didn't buy and sell any LTC, but if the person updates the site for a few seconds, the entire history appears and then disappears. very strange
