Add Buy/Sell Buffers to 4 indicators

Good day Developers, I would like buffers for buy and sell alerts to be added to 4 indicators. I have attached their source files. 

At the moment these indicators do not have buffers for when buy and sell alerts start, however I feel they have the provision for them. I just the indicators to be able to give a buffer signal on the chart of a change of market. So when a buy starts, maybe a dot or arrow and the same when it is a sell. And also add buffer names to the final indicators.

I have attached them here and also added info on where the buffers should be added. 

I am on a limited budget so I will not go over my budget here.
