Which MT4 file stores the trendlines drawn on a chart?

I have MT4 on my Surface Pro 3 for use when not at home, and on my main pc when at home. What I don't want to do is re-draw all my trendlines, fibs etc on every chart, every time I update it on the main pc.

So what I would like to do is simply copy the files over which contain the indicators for each chart. I don't want to copy the entire MT4 folder over because I use far less charts on the Surface due to its much smaller screen and copying the whole folder open means I have to go along closing and resizing everything again. I have also seen a suggestion that copying my MT4 to a dropbox account would allow me to simply use the same copy of MT4 on both the pc and Surface, but again my issue with this is the surface has a much smaller screen and I would be constantly resizing everything every time I switched (main pc has 9 charts up at once, the surface has 4).

So I am wondering if I can find the files that contain the indicator positioning for each pair, and just copy over those ones then I won't need to mess about closing charts and resizing everything every day. As far as I have been able to work out, the .hst files under the server folder are NOT the file that contain the indicator positions for each chart, I think they only contain the bar data and nothing for indicators, I know this because switching servers to a new server still keeps the same indicators on the chart, providing the symbol has the same name on the other broker/server. So the actual chart layout for the positioning of indicators on each chart must be stored elsewhere.

Ok looks like I found it. This seems to be stored in the .chr files within the profile folder of the currently selected profile. Which still doesn't help as the files are intelligently named chart01, chart02 etc so I cant just copy over the relevant ones from the desktop! I would have to copy them all over, resulting in 9 of them being displayed again, in pc size, instead of the 4 I want on the laptop. This is just stupid.

Why don't you create a template file for each chart you want to save. Then copy these files over & load the templates
to each new chart.

Name each template specific to the chart you want to save with all objects, trendlines, fibs etc.
When you draw new objects remember to save the template each time.

Hmmm not tried that yet. Good point I forgot the lines were also saved in templates. That seems to be the only solution. I only need 4 or 5 so this way isn't too bad. thanks.
