Script written for a stock trading platform indicator

I am looking for a script written for an indicator to be applied to a stock trading platform. The indicator should work across all time frames - specifically, it needs to be a dashed vertical line set at a specified number of days,weeks in the past and move forwards each day, [login to view URL] is used to see where the stock was, for example 50days ago on a daily chart - I then add the 50 day Simple moving average to the chart and as the time progresses I can look back to where the vertical dashed line is to see what old data will be removed that day and what effect the new data on that day will have on the slope of the Simple Moving Average. For eg. I use on my 30min chart the 5 day SMA, so I’d like to quickly be able to see where 5 days ago was data wise and make a thesis based on that old data being removed from the calculation and if the stock continues up for the current day, what effect would that have on the slope of the 5 day SMA. I’m essentially front running the SMA to make it more effective rather than a passive lagging indicator. The other essential one is the 50 day SMA - so for this one on my daily chart I need to see where the stock was 50 days prior. Needs to work on weekly chart also as I use the 10,20 and 40 week Simple moving averages on that chart. Ideally the dashed vertical line would match the colour chosen for the SMA so I can tell which line corresponds to each Simple moving average. I use TrendSpider charting software which has a very user friendly Java script creator which I think would make this a quite simple script to write for someone that understands what I’m trying to achieve and also understands Java script. I’m a complete novice at script writing and don’t have the time to learn. The way I picture it working is when I choose to add a Simple Moving average to any chart there is a preferences box that opens up and allows you to choose what colour you would like for the indicator, how thick the stroke of it is [login to view URL] already is the case - and so there would also then be a box to check and next to it would say something like “ Show vertical dashed line”. Once checked, it would then apply a vertical dashed line 5, 10, 20 or 50 periods (depending if you are on a weekly or daily chart - for charts less than a day it only needs to show 5 days prior as I only use the 5 day SMA on charts less than the daily) in the past along with the SMA. The attached image shows my 30min chart with the 5 day SMA and also a full vertical line 5 days ago - I’d like the line to be dashed please and match the colour of the SMA. Note: For the 30min chart the true 5 day SMA is actually entered as a 65 period SMA due to the number of hours in each trading day, similarly for the 5min chart I actually enter a period of 390 for the 5 day SMA however I only need the indicator to show the 5th day prior to current day. This is straight forward on a daily or weekly chart as the period entered for the SMA is the same as the period for the vertical dashed line. It gets complicated on charts less than daily as you have to calculate the number of trading hours per day and apply a different multiple depending on which chart you are using that is less than a daily chart but I only currently use the 30min and 5 minute charts — these are the only two i use less than a daily. Really appreciate anyone who can make this happen for me as I’m so sick of trying to count back 5 days every tiime I open a new stock chart and as you can imagine it’s almost impossible to count back 50 days on a daily chart - you would be there all day!
