Re: [amibroker] Why does this formula produce a "Referencing Future" Error, AmiBroker Email List Archive

Thanks Tomasz
This is a bit confusing for me. I have been using lastvalue() in if statements to pick the current bars value.
Like this example .. I'm trying to 'latch' that I had a buy signal in my real time system.
LELatch = StaticVarGet(LE) ;
if (LastValue(Mybuy) AND not LELatch )
{
           StaticVarSet(LE,True);
       // latch that we had an exit signal in real time
}

Is there a better method than lastvalue?

LastValue looks for the future - Last bar is "the future" for every bar other than the last.
