    Hi

    I’m executing this screener against European Indices (daily), but the problem appears with other lists too.

    So, I get no results, but even if I comment line 3 and uncomment line 4, I still get no results.  This doesn’t make sense to me – has anyone got any ideas what I’m missing?

    Thanks

    I don’t know what you want to do but I know that your code does not do what you write in the comments. I think you have to switch the numbers in the [] brackets for your middle variable.

    What are the conditions you want to screen for?

    Line 1 scans for the highest price 240 to 260 bars before.

    Line 2 scans for the highest price 20 to 240 bars before and it should be <= that in line 1.

    Is that correct?

    Despair is right, what do you want to do? Maybe a plain text explanation is clearer than code!

    Proscreener has a limit of 254 bars of data, try to limit your periods lookback at lines 1 and 2 and it should be ok.

    Thanks everyone for all your responses – robertogozzi described exactly what I was trying to do and I think Nicolas has identified the issue – I will try the same on weekly bars to see if the proscreener limitation disappears for the same period.

    The 254 bars limit exist on all timeframes.

    Yes, I understand, but I’ll be looking over the same date period, so much fewer bars. I’ll post whatever I find. Thank you.

    Thanks very much, that worked exactly as I was hoping. Are prorealtime/proscreener limitations like this documented anywhere?

    Hi again, unfortunately some confusion remains! So, I thought I’d risk another post.

    I think there must be something more to it than just the 254 bar limit – see the code below, a much simpler calculation, which uses only 60 bars of daily data.  The idea is to find stocks that have hit new highs today but not yesterday.

    When I run this against “Shares – US Wall St.”, I get many matches, but some of them I believe are in error e.g. “Hawaiian Electric Industries Inc.” – today’s and yesterday’s highs are much lower than the high over the last 60 days so the high>ha isn’t true.

    It looks like the problem has been fixed behind the scenes – running the code today, there are no erroneous matches at all.  Thank you to somebody!
