And Or logic sequence

  Hi Experts,

  I need some guidance figuring out the AND & OR logic execution.  I got an entry with code 1, but not code 2 and code 3 stated below. I couldn’t figure out how did that happen with code 1.

  // code 1:

  if x OR y AND z then

  buy 1 shares at market

  // code 2:

  if (x or y) AND z then

  buy 1 shares at market

  // code 3:

  if x AND z then

  buy 1 shares …

  if y AND z then

  buy 1 shares …

  Just in case it was random (with code 1) can you reproduce (a few times) entry with code 1?

  Hi Grahal, in Backtest yes code 1 resulted entry 10/10. Let me relaunch the PRT to test it.

  In principle (and by design), how should code 1 run? Eg. it is (x or y) and z? x or (y and z)?  Note,  The brackets are not written with code 1, I just put them here to elaborate the logic.

  Thanks!

  Both above mean the same in PRT Code and should gives the same Trades.

  code 3 : X AND Z

  code 4: Y AND Z

  Either of above should give some Trades coincident with code 1 and code 2, but not the same Qty of Trades as either code 1 or code 2 … assuming you use either code 3 OR code 4 in 1 System.

  If you use code 3 and code 4 in 1 System (as x and z OR y and z) then the results should be the same as using either code 1 or code 2.

  I suggest to use parenthesis to avoid any misunderstanding when having to mix AND and OR (I always do that).
