Different trades in cAlgo vs cTrader, using same indicator

Hi,

The indicators used in cBots show different entry and exit trade points during backtesting is cAlgo than the same indicator in cTrader. Why?

Can an indicator be shown in cAlgo, so that I can manually check if the backtesting signals are correct?

Currently I compare by having both cTrader and cAlgo open. For simple bots like a stochastic cross over, cAlgo enters and exists trades at different times than the same stochastic with same parameteres, time frames and data source, shown on cTrader.
