Sorry to be one of the Gann Fan posts! haha! I just can't seem to figure this out. I am trying to recreate the "zero price fan" found in Optuma so that I can switch over to 100% Sierra. I'm looking to set Anchor A to zero, which is easy enough. But then I also need the 1x1 line to be set and locked to 45 degrees. On most charts this is proving to be impossible due to the price scale. I would greatly appreciate any help to accomplish something similar! Thanks so much! |

A 45 degree Gann Fan line has a slope of 1, therefore you would enter a value of 1 for the "Slope" in the Gann Fan Properties/Configuration.

I’m sorry, I don’t understand. When I draw the initial fan, a black box comes up with it and shows the actual angle degree. .25, .33, .5, 1, etc slopes are all preset and checked in the fan properties. It does not auto correct the 1x1 line to 45 degrees.

If the "Black Box" you are referring to is the Tool Values window, then it will show the angle that you are drawing between the first point and the second point. If this is set to 45 degrees, then the Gann Fan line with a slope of 1.00 will go directly from the first point through the second point. It really does not matter what your second point is. The Gann Fan line with a Slope of 1.00 will always be the 45 degree angle as defined by the rise in price in ticks divided by the run of the number of bars. As stated in the documentation we pointed you to, this will not necessarily look like a 45 degree angle on the chart itself, and most likely will not.

Thanks for the reply, John. So you’re saying that I can start a Gann fan with point 1 at the center of a clock and point 2 at 1 o’clock - and another fan with point 1 at the center of a clock and point 2 at 2 o’clock and the 1x1 slopes of both fans are 45 degrees? Visually they are two different angles so one or both “must” be incorrect. Again, when I click two random points on the chart, it does not auto correct the 1x1 line at all. It stays fixed at the points that I select and labels it 1x1. Date Time Of Last Edit: 2024-05-11 20:13:25

Yes, if the distance to the 1 o'clock and 2 o'clock positions are different such that you end up with a consistent rise over run. But if you did the sam distance (same radius of a circle) then the angles would be different. We are not understanding what you are referring to as the "1x1" line. There is only a single number for each line of the Gann Fan. The displayed number for each line is the slope of that line. The line that has a slope of 1.00 is a 45 degree line. Again, it may not (and most probably will not) show as a 45 degree line in the display, but with respect to the price Tick Size and the bar spacing, it is a 45 degree line. Keep in mind the axes you are dealing with are mutable. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

https://www.sierrachart.com/image.php?Image=1715614391888.png Thanks again, John - and I'm sorry to be a pest about this. In the attached photo, the Slope 1 lines are highlighted in red for 3 different "randomly drawn" Gann fans on a single chart (FGBLM24). I'm just having a hard time understanding how ALL of these can possibly be 45 degrees. |

For each of those drawings, right click and select "Drawing Properties". On the "Options" tab is a section for "Value Increment Per Bar Set From" and most likely each of these is set to "Second Point". Please verify that this is the case. If it is, then reason why you get different looking Gann Fans for the same slope is because the second point you select sets the ratio of the number of ticks to the number of bars which sets how that angle is going to be determined. Let's look at this a different way. When you state you want a 45 degree angle, what is the relationship of number of ticks to number of bars that you are looking for? Is this a 1:1 ratio or something else (for instance, so you want a 1 point price difference to match up with a 1 bar move)?

Fantastic! You're the best! Now we're getting somewhere! Yes, sir. I am looking for the 45 degree angle/1 slope to be a 1:1 ratio. Yes, "second point" was selected. If I select "from chart setting", will this now calculate the 1 slope using the 1:1 ratio? Also, do you have a link that describes how the "from tool ____ Tick Size" function works? Thanks, John! |

If you want a 1:1 ratio of Tick Size to Number of Bars, then this would be accomplished by using either of the Gann Fan options for "Value Increment per Bar Set From" of: - From Tool: set this to "1" * ticksize - From Chart Settings: and set "Chart >> Chart Settings >> Chart Drawing >> Value Increment per Bar in Ticks" to a value of 1.0 Again, this will give you a 45 degree angle as defined by "number of ticks"/"number of bars". This is explained at the following link: Chart Drawing Tools: Viewing Angle in Degrees, Related Settings, Understanding Angled Lines on Charts Note that it took me a long time to understand this myself. Just keep in mind that you are dealing with bars and ticks, not time and price.

Got it. Thank you, sir!
