Re: [amibroker] How can I do BarsUntil ? (like BarsSince)

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

function BarsUntil( array ) 
{ 
  result = Null;   
  bars = -1; 
  for( i = BarCount -1 ; i >=0 ; i-- ) 
  { 
    if( array[ i ] ) bars = 0; 
    else 
    if( bars != -1 ) bars++; 
   
    result[ i ] = bars; 
  } 
  return result; 
}     

Note the function will return -1 if the array is NOT true from "now" till the end of  available data.

Best regards,
Tomasz Janeczko
