$BTC heading into fomc

Chart is suggesting $BTC moves up in the morning to about 29.2k before the fomc meeting. Then a quick whipsaw back down to the mid 28k level. I've been seeing people call for every price up and down within 5k. Over the last 24 hours BTC has made a low of 27,924 and a high of 28,881, it's currently being traded for around 28,790 on most exchanges. It's tough to know exactly which way we're headed.
