Hi OpenLedger,

I traded some more CVCoin with open.BTC on OpenLedger DEX, and realized that all transactions were not paid in full, I have made 2 transactions this morning, 1 time to buy 796.9099 CVCoin at 0.00019 open.BTC price, but I only received 780.9718 CVCoin with the above price and spent 0.15141289 open.BTC, I see as lost over 16 CVCoin (trading at block # 19394084 and once again buying 576.4436 CVCOIN is also at 0.00019 open.BTC, but only received 564.9148 CVCoin, I lost 12 CVCoin (transaction at BLOCK # 19397002), so in 1 session Morning with only 2 transactions I lost 28 CVCoin.. I do not know what the terms of their own except CVCoin that I ordered.

Please explain this issue
