Laravel query builder for time from dateTime

Trying to fetch data from table trades but only out range of another table exchanges which has two columns start_time & close_time.

TABLE exchanges:

TABLE trades :

I want to fetch only data of trades which are out of range start_time to close_time from table exchanges

For example, trades table has tradedate 07:00:00 then fetch because, exchange_id has 1... exchanges table start_time 9:15 and close_time 3:30 (range)

If tradedate time out of range (start_time to close_time) then fetch. How can I extract time only from dateTime "tradedate"? I am trying with query builder but...

` $user = optional(Auth::user())->id;
        $value = DB::table('exchanges')
            ->leftJoin('trades', 'exchanges.id', '=', 'trades.exchange_id')
            ->where('trades.user_id', $user)
            ->whereRaw("? NOT BETWEEN start_time AND close_time", 'trades.tradedate')

            ->get();`
