As in prior recent issue post,I've been doing intensive backtest audit for months, often slow motion, and rarely see what appear 3 or 4 rare bugs. (worked with SC a year,& others before that) I've studied all your back-testing, management, etc documentation. This is not just valid "ignored" orders, etc. My settings work great 99.9% of the time: Fill Blanks with Last Value Reset Condition on New Bar, etc. (See last post for other settings) One bug I did not report was a pending exit from 1 contract long, position +1 showing, and a -1 working exit order that would not fill for several bars (not the same as a never-off/on True which might be ignored). There was no ignored order message in Trade message log,either (like last post). Today I see an error in a >= test a condition that SC reports false, while it computes true in the same condition-equation, testing for (E3-E4)>= 0.75. At first I thought maybe getting rid of no leading zero on .75 might help, but no. That is, the difference IS .75, the test is for .75. but >= returns False. The test & condition are simple, it's past end of bars, unlike the prior intrabar or at change of bar bug(s). I've attached a screenshot. It's rare, becaused I've viewed thousands of these (many days) with nothing like this before in a simple operator-function. My system is large & complex, has cascading charts, and I can't send the entire system. I'm sure you've done it, but I urge you to someday have someone spend a few days doing what I've done, looking for these 3 or 4 bugs and others, slowing it down, testing an assortement of operators. |
