I am having trouble finding an answer to a simple problem - or definition.
I want to use an event that may have occured within the last n bars such as EMA(20) crossed over EMA(200) within the last 4 bars. I have 3 events which I need to have occured within the last 3-4 bars to satisfy a trade condition. I cannot get the syntax right!
I would be grateful for help
Thanks
Karl
