  Well, it's more complicated than you might think.
  
  You have five different cases:
  
  52 week high 4 days ago then 3 consecutive lower highs
  52 week high 5 days ago then 4
  52 week high 6 days ago then 5
  etc.
  
  Each of those has to be coded separately.
  
  The first one would be:
  
  and [4 days ago high = 4 days ago max(251,high)]
  and [Streak Down(high) = 3]
  
  For the next one, you have to adjust the numbers for 5 days ago, etc.
  
  and [5 days ago high = 5 days ago max(251,high)]
  and [Streak Down(high) = 4]
  
  
  If you want all the cases in one scan, you have to link them together in an "or" statement:
  
  // begin scan
  
  [exchange is NYSE] // or whatever
  
  and
  
  [ // begin or statement
  
  [ [4 days ago high = 4 days ago max(251,high)]
  and [Streak Downn(high) = 3]]
  
  or
  
  [
  and [5 days ago high = 5 days ago max(251,high)]
  and [Streak Downn(high) = 4]
  ]
  
  or
  
  etc.
  
  ] // end or statement
  
  // end scan
  
  When you write it yourself, just do one case at a time starting with the first, then add the second, etc.
  
  Stockcharts has made it easier and easier to write scans, but they don't write themselves. You will have to put some time in if you want to master it. You could start here:
