Hi, I have the strategy attached Default_1.12  1. Calculating the time between last hourly candle and Get Historical Candle with shift 0 should be 0 not -1. 2. Using Last Tick Time instead of last Candle time gives results between 0 and -8.0008797... something Regards, mosu_d

Hi,
Thanks for your post.
Basically the result should be indeed 0 but troubleshooting the problem more deeply it appears that the time stamp of both variable is correct but there is some lag time in the update of the time variable related to the historical candle. As far As I seen the delay is not consequent as the variable gets updated with the correct time less than a second BUT after the calculation is already performed with the wrong result.
I think that this is not really blocking, can you provide some description about the idea behind that ? maybe we can figure out another way around ..
We'll address this meanwhile ..
Cheers

Hi Amine,
For report 1
Yes, I also observed the same with regards to the first point.
I discovered this while working on a solution for a custom SandR with blocks for thread (S&R indicator in Visual JF?).
I can work around it now that I know the problem. Simplest solution would be thread:
Enhancement request for adding round function to Calculation Expression.
For report 2
For this I have no clue because the results are all over the place.
Cheers,
mosu_d

Hi there, 1/ Check the attached example for the rounding issue. 2/ Quote: Using Last Tick Time instead of last Candle time gives results between 0 and -8.0008797... something Can you provide the calculation block so that I can understand exactly what are you trying to do ? Thanks

Hi Amine,
Regarding point 2,
strategy Default_1.12_tick.
There may be some other problem other than just some milliseconds.
If the test is executed with DefaultPeriod 4H instead of 1H, the result is -4 instead of -1.
Issue 3
Getting the candle time on 4H and 1D returns incorrect values: Default_1.13
