Just fooling around with a very simple idea, but can't get the code to 
  work.
The idea is to sell at close of every day, hold over night, and sell 
  at open the following day.
Code below sorta works, but skips every other 
  day.  For example:
Day 1, buy on close; Day2, sell on open.
Day 3, 
  buy on close; Day4, sell on open.
etc.
But I can't make it buy on close 
  of days 2, 4, etc.
Tried "Allow same bar exit" in settings, but that makes 
  it sell the same day that it buys, which is wrong.
// BuyClose SellOpen Daily.afl 
  
SetTradeDelays(0,1,0,0);  // has no 
  effect 
Buy = Close; 
BuyPrice = Close;
Sell = Open; 
SellPrice = Open; 
Short = Cover = False; // long only strategy 
  
Buy = 
  ExRem(Buy, Sell);  // has no effect 
Sell = ExRem(Sell, Buy);  // has no effect 
Well?
