I'm using the Laracasts\Validation\FormValidator package

how would I setup validation rules for each unique stock field?

<?php namespace Acme\Forms;

use Laracasts\Validation\FormValidator;

class SubmittradeForm extends FormValidator {

protected $rules = [
	'stock_id'    => 'required',//is unique for each stock
	
];

}

   @foreach($stocks as $stock)

<div class="pull-right hidden-sm text-right m-t" style="padding-top:10px;">
	  
		    <div class="">
		        
		        <label class="btn btn-success" ng-model="radioModel"  btn-radio="'true'">UP</label>
		        <input type="hidden" name="{{$stock->id}}" id="{{$stock->id}}" value="@{{radioModel || 'null'}}">
		    </div>
		    <div class="" style="padding-top:5px;">
		        <label class="btn btn-danger" ng-model="radioModel" btn-radio="'false'" uncheckable>DOWN</label>
		   
		    </div>
		     {{ errors_for('$stock->id', $errors) }}
	 </div>
@endforeach
