Repeated Buy signals and unusual sell signals

Hello All,

I have system, which generates Buy-Sell signals based on few simple conditions as shown in the code below. For some odd reason, I am getting consecutive BUY signals (Green Triangle in Screenshot 1) despite having Exrem between BUY and SELL condition.

The second issue I have is with regard to SELL condition (Please see code below). Many a times, the conditions are clearly satisfied, yet there are no sell signals ( see screenshot 2) . Please help me to identify the in mistakes in my code.

Buy = trend == 1 AND finalCSum > EMA(finalCSum,EMALength) AND TimeNum() > entryTime AND TimeNum() < lastbuyTime; 
Sell = Cross(finalLSum,TrendSL) OR TimeNum() > sqroffTime;

Buy=ExRem(Buy,Sell);
Sell=ExRem(Sell,Buy);

If any more information is required, I will be happy to provide.

Rick
