It seems like you misunderstood the Pluck method. Pluck is to take several properties out an array by their key. Nothing to do with selecting columns from a Database.
I guess you want to select a single UserProfile. And the right way of doing this is as follows:
public function edit(Request $request, $id){
$user_profile = UserProfile::findOrFail($id); // Select a UserProfile by ID or fail
$exchanges = Exchange::all('exchange', 'id');
$markets = Market::all('market','id');
$countries = Country::all('country','id');
$brokerage_company = BrokerageCompany::all ('brokerage_company','id');
// I dont know what you want with this statement?
// $user_profile = UserProfile::pluck('charge_intraday','charge_delivery','charge_per_lot','charge_per_order')->all();
return view('profile.edit', compact('user_profile','exchanges','markets','countries','brokerage_company'));
}
