Horizontal line drawing by EA or Indicator

I want to have a software delivered with source code, I am not sure if it will be an indicator or an expert advisor but this software will be able to draw horizontal lines across any bar high whose previous bar and the next has a lower high. It will be vice versa for the low, so the software will draw a horizontal line across any bar's low whose previous bar and the next has a higher low. I have attached a picture named 1 to explain this point.  It will be across the entire graph and all the bars as far as the graph can go historically. If there is need to load the bars first by scrolling backwards as far as MT4 will allow I will do it manually and then when I apply the EA to the graph, it will draw these horizontal lines. The EA will ignore the latest/current bar on the graph and I guess the bar before but I think I will be able to get a better understanding of this once I start using the EA. 

The high will be calculated to the last pippet which will be based on the numbers from data window or that small window that pops up showing high, low, open and close when you hover over a bar which shows the same data as the data window but its important that its to the last pipet not just pip so that more accurate highs and lows are drawn. 

If there are multiple bars that have the same high, for example  lets say there are 5 bars which have the same high(5 bars is just an example it can be any number of bars but obviously that many bars having the same high/low is unlikely) then if there is a previous and the next bar, before and after those 5 bars who have a lower high then there will be a line drawn on those 5 bars high. This point is explained in picture 1. 

In the comment section of the line, it will say which timeframe it belongs to and it will have the date and time where the bar is located. For day, week and month, it will obviously only have the date not time. For bars where multiple bars have the same highs as explained in the above paragraph, the last bar will be used to plot the date and time. This point has been explained in the picture named 2. 

I will be able to choose in which timeframes I want these lines drawn and also I will be able to choose the colour of the horizontal line for each timeframe. This point is explained further in picture titled 3. 

Once drawn I will be able to remove the EA but the lines will stay. I will be able to manually delete the selective lines as well once the EA is removed. 

If I want to delete the lines drawn in a particular timeframe or all the timeframes by the EA, I will be able to delete them by reapplying the EA and selecting the timeframes I want lines removed from. The EA setting window picture gives a better idea as to what I mean. Only the lines drawn by the EA and of the selected timeframe from the EA will be deleted, not others which I have drawn manually previously. This point is explained further in picture titled 3. So when I want to draw lines I will select the Draw lines sections as Yes and Delete lines section as No, and when I want to delete lines it will be vice versa. 

The product requirements are listed in this text and in the pictures so both need to be addressed and completed. I have tried my best to list all the features that are needed by the indicator in text and pictures combined but there might be things that might require changes. I would kindly request the developer to keep in mind that I can ask up to 50 changes. I am not saying that this would definitely will be required since if the indicator functions as it should then no changes would be required but if it requires changes, which I am hoping it doesnt, then those changes can be upto 50. The 50 changes come into action if I have a functional indicator which does what I have requested for. If it turns out as something entirely different, which I doubt will happen, then the changes to get the correct product produced will not count as part of the 50 changes. I have a feeling though with the pictures I have used that will not be required.  

Also I might include requirement changes in the alert indicator since once you use a product you often spot additional information that you want from the indicator and for that reason the developer should keep in mind up to 50 requirement changes but again I seriously doubt if that would be needed since I think I have listed everything in the text. 

I would again like to request the developer that I would require a spell of 3 days 3 times while the market is open so that I can point out the problems. Again it is not necessary that this will definitely happen but if it does happen, I would be able to request changes properly this way. Again I am hoping I dont have to use all the 3 attempts since I have tried to explain everything in the pictures and the text.
