This is an ongoing issue that has been reported once before and a solution to my problem has not been found. some of my daily and weekly charts are showing data that does not exist. Price has never traveled to the levels showing on day’s bar. attached are a few examples from today. this is only accruing on daily and weekly charts that are marked Historical in the chart setting. how do I fix this issue so it reflects the same data im showing on the intraday charts. In the past a sierra engineer had said that this is how the data comes in and there is nothing they can do. that same data is registering correctly on intraday charts but not on historical charts so I believe the issue is somehow related to the chart settings. Thank you in advance. |

The closing price is not the problem, the high and low are the problem. look again at the pictures attached. the range of the daily and weekly bar is sometimes 3-10 times the range of what they should be. for example in the qqq chart picture the high of day is roughly 491 and the low is about 448. the actual high and low are 491 and 487 roughly. the difference is 11 times greater. this is no small mistake this is a huge problem that needs to be addressed. please take a closer look at the images attached and compare them to the actual daily quotes. I am unable to conduct business with errors like this. also, please note that at the end of the day the charts fix themselves and the weekly and daily historical charts reflect the same data in the intraday charts. thank you in advance. looking forward to hearing back from you and getting this fixed. |

Thank you for responding. I understand that this is how the data is but that data is not reflecting the same prices on all timeframes within a symbol. my intraday charts are reflecting the correct highs and lows but my weekly and daily are reflecting completely different data which means that its not the data that is wrong its how the daily and weekly charts interpret this data and populating it on my chart incorrectly. if all my charts (timeframes) for the same symbol would reflect the same high and lows I would accept the fact that that is how it is and there is nothing that can be done. but thats not the case. why is it that my historical charts represent a totally different price range then my intraday for the same symbol ? also, why does that daily and weekly bar correct it self around 4pm PT every day? |

Daily Historical Data is a separate data set from the Intraday data. The exchanges send us that daily data that we store and then display in daily and higher timeframes. Therefore, what we are telling you is that we have verified that the data we get from the exchanges is what we are displaying. We can NOT explain why this data is different from your intraday data. That is something you would need to ask the exchange themselves.

We are considering removing this high/low data from the exchange, but right now it is supported and it is all implemented correctly. We have to look into this, but it would probably be because the official high/low data from the exchange is changing: why does that daily and weekly bar correct it self around 4pm PT every day?

if I set my daily chart to intraday chart only setting in the chart data type would it solve my problem and give me the same data as my lower timeframe charts that reflect the correct data ?

fantastic, so that is the work-around to avoid my issue. only problem is that it takes longer now to flip between charts. what is the difference in data the chart is pulling between historical and intraday that makes the intraday longer to load? I tried doing the same for weekly but its making my platform non responsive. im guessing the data is too heavy. any ideas on work-arounds for the weekly chart so i can get the same data as the intraday? |

Depending on your setting for the "Intraday Data Storage Time Unit", the intraday data contains the trade information for the specified time period. If you are storing your data at every tick, then every trade is stored. The Daily data is only the Open, High, Low, Close, and Volume for each day. So there is definitely a difference in the amount of data to load. You can change your "Intraday Data Storage Time Unit" in order to get faster loads. What you set will depend on how you use the intraday data.
