the_doctor - I have only recently bought shares in OXB after a tip. These were tipped to me in September at 43p and I was unable to complete my research until the sp had fallen below the trend established at that time. I rely on TA and with the news of placing I wanted to establish a "base price" for entry.
But the trend remains intact only if adjusted to reflect this news and I am still plotting (manually) this data.
Sorry if I appear to be going around in circles, but too many short term bad decisions have led to exposed long term holdings!
