Many thanks for taking the trouble. Your code works flawlessly. Now comes the undersanding it bit to see what I was missing.

Rakesh,Glad you posted the code. Otherwise, we would'veexchanged another dozen e-mails without gettinganywhere.The primary problem is having a cross of a triggeroccur when we are not in the appropriate condition. There are two ways to handle this.First, you put a time limit on the number of bars thatthe entry can be taken after it's established. Forexample, EntryOK = BarsSince(BuyCondition, 1) <=5;Another method to to define which state your are in,and from there marry the state to your buy/sellcrosses to ensure that a cross is occuring when youwant to take advantage of it.I've coded the changes using the second method sinceit's a bit more confusing, and it'll help to see thecode. Also, I've added exrems to get the extra buyand sell signals out. You may want them
back. If so,just get rid of the exrem.BTW, you may wonder why I use not instead of two flipsto define buy states vs. sell states. Reason being,in a case where both the buy condition and sellcondition are true, Flip(buycondition, sellcondition)yields a false as does Flip(Buycondition,sellconditon). As such, nothing would happen. Toaccount for this we use not BuyState. In other words,if we are not in a buy state, then by definition weare in a sell state. Just play with the code, andyou'll see what I mean.Kind Regards,GaryEMA1=EMA(C,8.3896);EMA2=EMA(C,17.5815);DMACD=EMA1-EMA2;M_TRGR1=EMA(DMACD,3);M_TRGR2=EMA(M_trgr1,5);D_M_HIST=DMACD-M_TRGR2;B_XOVER=Cross(DMACD,M_TRGR2);S_XOVER=Cross(M_TRGR2,DMACD);OnBuyXOver = Flip(B_XOver, S_XOver);OnSellXOver = NOT
