[amibroker] Re: MA cross with %filter

Hello:

I'm still having difficulty understanding both the flip() and exrem() function.  Can somebody help to explain them.  I've read documentation, but it is fairly brief.  

Does flip remove all signals until a opposite signal is generated?  Not sure if I'm understanding it.

Thanks

Levi

I would like to have a filter that I include with buy logic as follows:  Using S&P500 data, whenever price moves above 65 week moving average by 1%, filter = 1.  Whenever price moves below MA by 1% filter = 0.

Then price comes back up above 1% buy filter.  During this period, the filter should always = 1.  But if it crosses 1% sell filter, it should become 0 until it crosses above 1% buy filter.
