When your account is created, by default repricer would run in report mode only as it's for demonstration purpose. You would need to make the repricer live manually by logging into your ChannelMAX account as below to feed the prices to Amazon Seller Central automatically.
Open Google Chrome or FireFox
Login to selling.channelmax.net
Click on 'Settings -->Repricing--> Repricing Model'
Set Rule#44a Enable to "Yes"
When this rule#44a is set as enabled, ChannelMAX repricer will start feeding the prices from the next reprice process. When we start auto feeding prices from ChannelMAX to Amazon, an entry 'RePrice' with status column _DONE_ is displayed in 'Settings-->Processes-->Job Process Log'.
