Price data - force "close" value to be "open" of following day

[ashachaf]

currently, we fetch data as it comes and sometimes there are gaps in the information between the close of day 1 and the open of day 2. this is not a normal behavior for daily data as close of day 1 should always be the open of day 2.

issues current behavior cause:

1. there are unexplained gaps between days where the candles are not aligned in a continuous way

2. when the open != previousDay.close, the candle can incorrectly be colored in the wrong way to indicate incorrect direction of trades.

expected behavior:

    time       high   low    open   close
