BARS returning 0 ? - page 2

Wow.... that's worst to me, since now I will have to understand what is going on here.

Thank you VERY  much for your help Alain.

I wish you a Merry Christmas and a healthy (and profitable!) New Year!

You are welcome.
 

Just an info to help others:

I really had made a mistake. Although all bars were available at the META CHART, I was trying to conduct the BARS() operation using the same date interval of my term as set in the backtest.

So, when the backtest started and the BARS() function was called, in fact I hadn't all the subsequent bars (until the End_Date) available in its CHART window. My mistake was to see the META chart with all period bars and forget that I was creating a new chart-window in TESTER.

A basic mistake due to the long (and hard) time dedicated to code today.

Again, thank you Alain for the support and tests, which lead me to dive deeper in the problem.

You are welcome.

Hello Alain!

I've Set The "input datetime" to my £xpert advisor but this parameter seems not to work, because the £xpert advisor is always active (Placing orders) £ven in the deactivated time.

Would you help me? 

Thanks in advance.
