If i double click the file ,there appears a small qsetup window that shows extracting files, but nothing else happens . I also have no idea where to find these extraced files. I am using it on an Win11 PC with all updates applied. any hint? Thank You

All versions have a 1 year limit to the lookback period in live trading. The manual mentions that PRELOAD allows a longer period, but I think this is wrong. I'll check. - Zorro_260.exe does not unpack: Another user had the same problem. We have just re-uploaded 2.60.2 with a different setup program, please try again.

I had the same behaviour in 2.53 indeed. With PRELOAD, why is it limited to 1 or 2 years? Should I e-mail support team or open a new forum thread for a request to extend number of years beyond 2?

I actually don't even need long lookback but I need to scan & gather data points from a few years back so I force Zorro scanning history with a long LOOKBACK period... Any suggestions? Perhaps a new flag imitates LOOKBACK run but without making LOOKBACK any longer? However, I still think there can be other cases which may suffer from current PRELOAD design. Here's another example with short lookback (100) and weekly bars. History was downloaded from broker without PRELOAD flag. It is actually more than 1 year, contrasting what manual suggests (max 1 year). LOOKBACK is fulfilled and run() function worked as expected. I trimmed the logs to make them shorter but you'll get the point. Code void run() { set(LOGFILE, TICKS); Verbose = 3; History = ".t6"; BarPeriod = 10080; // Weekly bars LookBack = 100; LookBackResolution = 60; // Speed up download from broker printf("Time: %s \n", strdate("%d %b %y", wdate(0))); } Log: Quote testlb2 Login 0 Oanda V20.. !account 101-004-9964544-004 at UTC 01-11 22:46Time: 11 Jan 24 V 2.600 on Fri 24-01-12 01:46:37 (Zorro S Subscription) Load AssetsFix Warning 054: EUR/USD LotAmount 1000 -> 1.0 Warning 054: EUR/USD PIPCost 0.1000 -> 0.0001000 !EUR/USD 08-31 22:46:39 to 01-11 22:46:39 !=> 12-22 12:00:00 to 01-11 23:00:00, 300 ticks Load EUR/USD prices.. !EUR/USD 08-31 22:46:39 to 12-22 11:30:00 !=> 12-06 01:00:00 to 12-22 12:00:00, 300 ticks 20944 h, 8624 bars added EUR/USD 29568 ticks read Warning 014: bar 67 gap at UTC 2021-01-01 15:40:00 226(29620) bars 2019-09-13..2024-01-12 generated EUR/USD: 0..29619 Trade: testlb2 EUR/USD 2024-01-11 Loading Data\testlb2_d.trd (V2.600) Lookback 100 bars, 2022-02-18..2024-01-12 [126: Fri 22-02-18 15:40] 1.13895/1.14090\1.12811/1.13490 -0.00020Time: 18 Feb 22 .
