Here is my story about over-buying:
So as I said yesterday I bought 10000 BitUSD at 40 BTSX each.
Today I am of the opinion that this downtrend is over, so I decided to sell them. Then I started panicking when I realised that there generally isnt enough volume to sell 10000 BitUSD, so I had to entice the buyers buy selling under the current price feed of 44 and selling at 41.
Luckily for me, someone bought my hot potato
Therefore I made out with a profit of about 10000 shares.
Lesson learnt: think ahead and dont buy more than the market has volume for.
