Platform error on new cBot

During some test the platform gives one error just lile "We've informed Spotware, restart cAlgo".

My cBot tries to avoid the use of Stop orders and keeps secret the stop order level

 private void MarketDepth_Updated()
        {

            if (((SetBUY) && (Symbol.Ask >= PriceLong) && (Positions.Count == 0)))
            {
               
                ExecuteMarketOrderAsync(TradeType.Buy, Symbol, Volume, label, SL, TP, Slippage);
            }

            else if (((SetSELL) && (Symbol.Bid <= PriceSell) && (Positions.Count == 0)))
            {

                ExecuteMarketOrderAsync(TradeType.Sell, Symbol, Volume, label, SL, TP, Slippage);
            }

PriceLong and PriceSell are my hidden stop order levels at which the bot should trigger a market order so I can avoid the slippage related  with  Stop order.

then I added a grid type

What could be the problem?
