Ether is following same trend for last 5 days

Hi folks, I have been trading ether for last few months and today, while analyzing ether chart for last 5 days, I saw a weird trend appearing for ether trading between a window of 12:00 hrs to 15:00 hrs (GMT+8). I have put screenshots for easy reference to understand that ether prices are going up at 12:00 hrs (good time to buy) and usually fall or go above after 15:00 hrs.

Following the trend I am able to quench some extra bitcoins thru ETH-BTC trade, thought to share the observation with steemians who are interested in trading crypto currencies.

Note: Time in the following charts is based on GMT+8
