The bot definitely helped me see the price ratio between Steem Dollars (SBD) and Steem.
When you want to power up i.e. convert your Steem Dollars to Steem Power, the lower the ratio the better. For example, if you get a ratio of say 0.6, compared to say 0.8. Definitely converting it at 0.6 will give you more Steem Power.
