hello, i have a question on how to set the charts to load correct numbers of indexes. i have written an acsil study that uses arrays of another chart (tick nyse) - i understand, that in order to make the backtest result correct, i need to have the same number of indexes on both charts YM (as main chart and tick nyse as the chart i take the arrays from). but what i dont know is how to actually make it happened. when i load lets say 60 days to test it, the staring index on YM is different from the starting index in TickNyse. even though i have set the same RTH for both the charts, and linked the charts in advanced setting so that they should load the same number days, start at the same time etc.. and thus having the same number of indexes, it still doesn´t happen. therefore i cannot proceed a correct backtest.. what am i doing wrong? can you please tell me how to solve this issue? |

Make sure the Chart Settings are the same between both of those charts and reload both charts with Chart >> Reload and Recalculate. You are not going about this in the proper way. To access data from another chart, refer to this page: Referencing Other Time Frames and Symbols When Using the ACSIL You should never be relying on the indexes for the chart arrays from two different charts to be matching with each other.

well, ok, i must be either a complete idiot, or there is something wrong in the functions, or it is all much more complicated and complex that what is described there. because i got always some sort of mistake no matter how much i try to make it work according to what is described there. simple example i have tick nyse chart and i need to load its arrays into the the YM chart, and put an entry according to a value at an appropriate index. but sometimes there are holidays at NYSE and tick nyse has no data, while futures has data.. how will i set the propper indexing arrays? i mean, i suppose it should skip these no data periods when there are holidays and starts continuing backtest after at the propper index, but it doesnt. it just messes up the indexes when it hits theses days..
