Positions.Count is returning 0 inside Positions_Opened()

Dear cTrader Team,

I've noticed that Positions.Count is returning 0 inside Positions_Opened().
I've added some screenshots for your reference, as well as the cBot code, hoping you're able to reproduce this issue.

Should you require any additional information please let me know.

using cAlgo.API;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class MarginTest : Robot
    {
        protected override void OnStart()
        {
            Positions.Opened += Positions_Opened;
            Positions.Closed += Positions_Closed;

            Print("Symbol leverage : ", Symbol.DynamicLeverage[0].Leverage);
            Print("Account leverage : ", Account.PreciseLeverage);
            Print("Symbol currency : ", Symbol.QuoteAsset);
            Print("Account currency : ", Account.Asset);
            Print("Symbol pip size : ", Symbol.PipSize);

            PlaceLimitOrder(TradeType.Buy, SymbolName, Symbol.QuantityToVolumeInUnits(1), Symbol.Ask - 300, null, 1500 * Symbol.PipSize, 1500 * Symbol.PipSize);
            PlaceLimitOrder(TradeType.Buy, SymbolName, Symbol.QuantityToVolumeInUnits(1), Symbol.Ask - 600, null, 1500 * Symbol.PipSize, 1500 * Symbol.PipSize);
        }

        private void Positions_Opened(PositionOpenedEventArgs obj)
        {
            Print("**************** Positions_Opened ****************");
            Print("Amount of open positions : ", Positions.Count);

            double tradesTotalSize = 0;
            double accountMargin;

            foreach (var position in Positions)
                tradesTotalSize += position.VolumeInUnits * position.EntryPrice;

            accountMargin = tradesTotalSize / Symbol.DynamicLeverage[0].Leverage;

            Print("Calculated account margin : {0:0.00}", accountMargin);
            Print("Account.Margin : ", Account.Margin);

            Print("Error (%) : {0:0.0}", 100 * (1 - Account.Margin / accountMargin));
        }

        private void Positions_Closed(PositionClosedEventArgs obj)
        {
            if (PendingOrders.Count == 0 && Positions.Count == 0)
                Stop();
        }
    }
}
