Good day
Hope you can help me with this, tks
What I need is :

Open ONE buy position if the accumulation distribution in the current bar is LOWER than the accumulation distribution of the previous bar close

Open ONE sell position if the accumulation distribution in the current bar is LOWER than the accumulation distribution of the previous bar close.

in flat market , it is happening that in the same bar the accumulation distribution if passing above and below its value in the previous bar close , so I want it to open one buy and one sell position during this bar ,but actually what is happening is that if it opens the buy first it dos not open the sell until the next bar and vice versa
what is the solution pls ?
