Hi! I'm having a strange set of issues; 1. The percent change study does not correlate with the actual percent since open - It seems there is a difference between the main chart and the study on when the interpretation of "open" was. The actual is 0.45% as shown on the chart but the study is stating 0.77% 2. Time lines are not aligned to the actual time I've set denoting open and close. As you can see the open here is skewed to sometime after 22:15. Thanks in advance for your help |

1. You have your Percent Change since Open set to compare the Last price against the Open and to have it reset at the beginning of each day. Since you are comparing the Last to the Open, the Percent Change at the beginning of the day will not be zero, but will be the (Last - Open) / Open for that first bar of the day. Refer to the information on the calculation of this study here: Percent Change Since Open Also, you cannot compare that number against the Daily % Change. The Daily change is computed based on the previous day's Settlement price, which is not the same as the Last price of the day. Refer to the information on Daily Change in this section: Working With Charts: Chart Header Field Descriptions 2. The Time Line that you are showing has a time entered as 22:30. That value is entered into the study for where the line shows up. It is not automatic.

Hi, Many thanks for your quick reply! 1. What is considered the "beginning" of each day? I think thats what isn't clear to me, since ES and NQ open and close with a break but have continuous trading throughout the week. 2. Is there a way to have the lower axis aligned with the annotations on the chart? Thanks again |

Hi, Actually I just solved all this by setting the timezone in the chart and adjusting everything accordingly. I'm on GMT+8 which is where things were getting mixed. The indicator is now also showing the correct relative percentages from the open etc. Thanks again for a fantastic product! |
