    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).
