Answer 1

Try changing data: value to data: {position: value} in your ajax call.

$.ajax({
    url : 'https://1broker.com/api/v1/order/create.php?',
    type: 'post',
    dataType : 'html',
    data: {position: value},
    beforeSend : function(){
        $('.load').show('100');
    },
    success : function(pre){
        $('.load').hide('100');
    }
   });
  });

Answer 2

I believe the problem is that your ajax call doesn't match what your strong params are searching for.

  $.ajax({
    url : 'https://1broker.com/api/v1/order/create.php?',
    type: 'post',
    dataType : 'html',
    data: value,
    beforeSend : function(){
      $('.load').show('100');
    },
    success : function(pre){
     $('.load').hide('100');
    }
  });


  def position_params
    params.require(:position).permit(:symbol, :margin, :direction,:leverage, :order_type, :referral_id).permit(nil)
  end

You could either change your ajax call like Gokul M said

  data: { position: value }

or you could modify your strong params to not require position if you don't need to for other actions:

  def position_params
    params.permit(:symbol, :margin, :direction,:leverage, :order_type, :referral_id).permit(nil)
  end
