How do I get my Expert Advisor to show only the first buy and sell signals??  That is, assume I only want one trade open at a time.  So a 2nd buy or sell signal should not show until the first trade has closed.

Thanks

Hi,

There are a few ways you can limit conditions depending on the complexity and number of conditions. Here is one example using some moving average criteria:

bc:=C > Mov(C,20,S)+1{enter long condition};
be:=Cross(Mov(C,20,S),C){close long condition};
sc:=C < Mov(C,20,S)-1{enter short condition};
se:=Cross(C,Mov(C,20,S)){close short condition};
If( bc=1, 1, If(sc=1, -1, If(be OR se,0,PREV)))

One that uses a simple Buy/Sell criteria could be written as:

bc:=Cross(C,Mov(C,20,S)){buy signal condition};
sc:=Cross(Mov(C,20,S),C){sell signal condition};
trade:=If( bc=1, 1, If(sc=1, 0, PREV));
cross( trade= x, 0.5)

You will need to change the Trade=X, in the above formula to Trade= 1, or Trade= 0, depending on the condition you are defining, so basically you would use that formula once for your limited "Buy" signal and once for your limited "Sell" signal, the only difference between the 2 formulas being the value of X.

If these do not meet your criteria you may wish to request custom formula work at https://www.metastock.com/customer/resources/Formulas/CustomFormulaForm.aspx although there is a charge for this.

Happy to help! I realized I left off the explanation of "X" in one of the formulas and edited the original reply for clarification.
