Lesson learnt when FIFO on Vicom Limited

Vicom announced its Q2 result on 10 Aug 2016.
The result was announced after market closed and the share price closed at $5.91.
As expected, revenue dropped.
Unexpected is dividend also dropped.

I had added 2,700 shares of Vicom @ $5.75 in 30th Jun for FIFO purposes - Read here
Given that a lower dividend ($0.08) was declared, I am thinking the share price might drop when market open tomorrow.
Therefore, I went to place a sell order of 2,700 shares @ $5.88 (Target profit $0.13 instead of the dividend $0.08).

On 11 Aug morning, only 300 shares was done @ $5.88, pending 2,400 shares to be sold. I forgotten that Vicom usual daily volume was not high in the first place. Therefore I started to panic as I do not want to pay nearly $30 for the broker fees just for 300 shares. I went in to adjust my sell price 2 times in order to ensure all my 2,700 shares can be done by today. In the end, my average sell price was $5.83 (Profit $0.08/shares) and I accounted for 1/4 of the total Vicom volume for that day.

To FIFO, one have to note on the daily volume too.

Lesson learnt.
