Ray Tool: Extend Distance

Hi, I use the parallel ray tool extensively and I would like to limit the distance that rays are extended forward. Can this be done? It would make charting a lot cleaner and may help avoid the issue where price intersects these lines at some time in the future and moves them. Please see the example image showing in green where I would like short term rays to end - http://www.sierrachart.com/image.php?Image=1522324879998.png Note: Turning off extend is not a option because I always need the ray lines to contain prices and extend some distance past their anchor points. A config option to extend it at X% would be ideal. Thank you Date Time Of Last Edit: 2018-03-29 12:22:57

The best way to accomplish what you are looking for is simply to Extend the rays and then cut them using the Cut Drawing Here right-click option. You can find information on how to do this in this section of the documentation: Chart Drawing Tools: Parallel Rays For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Thank you John, that is a great solution. I'm delighted there is something already available to do this! One concern I have is that when I cut a ray line it moves the end anchor point to that location. I will have to test this further next week to see if it introduces issues whereby ray lines move position on the chart as new prices print. As is, extended parallel ray lines (that are not cut) do not move once I have drawn them and ensured anchor points are snapped to the OHLC of candles. Fingers crossed I will not have any problems though because I will only be cutting ray lines after prices have moved on and the channel is no longer in play. Any issues and I will report back.

Whether the ray is extended or not has no bearing on whether it moves or not. In addition, when a drawing moves, or appears to move, it does so in order to keep the slope consistent (especially when changing from Linear to Log scale and back). So you should not have any problems.

Hi John, Thanks for following up. Re: Anchor points changing Please see the screenshots attached to demonstrate what I mean. Note: I cannot upload these charts using the normal edit > screen images process because I have the chart drawing properties window open to show you the anchor points. Screenshot 1: Anchors_not cut I have setup the parallel rays as normal with 3 points (A, B & C) snapped to 3 candlesticks. Screenshot 2: Anchors_cut I have cut the rays using the 'Cut Drawing Here' option. Please see that anchor point B has now changed (both the time and value) where I made the cut.

Sorry, you are correct. This was also just pointed out to me by one of the other Engineers. I have removed that statement from the previous post. Still, the general statement is true. All the line drawings points are placed where they are, or move if necessary, in order to keep the slope consistent.

Hi John, OK I will test this next week and report back. I will say however that I have never had issues with rays moving when anchor points are snapped to candles. I can see other users have had success doing this also - see here Trend LInes moving even with 'no lock fill space' Now that anchor end points change when the 'cut drawing here' option is used I suspect this will re-introduce lines move around again. I do not know why anchoring end points to already printed candles/prices holds the rays in place but it certainly does so. Perhaps it's because: 1) The end anchor point has an exact tick value VS a non tick increment value (See 'Anchors_cut' Point B which is 2630.40 instead of .50 etc) or 2) The end anchor point has a defined chart time/value that already exists Vs the new end anchor point date/time value that is assigned to it in open/future chart space or 3) Both/none of the above. Anyways, I will see how things work out next week when the market is open again. Date Time Of Last Edit: 2018-03-30 16:50:40

Hi John, I have tested this over the last week. I can confirm the following: 1) If the parallel ray anchor points (A, B and C) are snapped to 3 candles, the lines do not move at all (slope, location on the chart etc) 2) If however, the parallel rays are cut (which creates new anchor points as discussed above), the lines can/will move I do not know exactly why this is the case. With that said, this is not a major problem for me to work around. What I can do is cut parallel ray lines at a point where price has already moved past and doing so seems to stop them from moving. This suggests my hypothesis No.2 in post #7 could be true. Either way, this one is resolved for my purposes so we are all good. Date Time Of Last Edit: 2018-04-06 20:35:32

Are you performing a cut at a chart column beyond the last chart bar?
