Market sessions indicator for MT4

I would like to develop market sessions indicator that shows the most significant trading sessions for the major financial market, such as London, New York, Tokyo, and Sydney.

The program work excatly the same as the following link (is from as author) and with the same design as well.

https://fxssi.com/fxssi-sessions-indicator

A few things below need to adjust

1. When user changing TF from H1 and above, Show a notification (message box - not alert) to inform User that this will not show in higher TF. And this notification only appear once per day. Meaning the session box only show M30 and below in MT4.
2. On top of the market session box, do label the distance (top to bottom) in POINTS
3. Default should shows 20 sessions.
4. Color scheme
1. Previously the Auto does not really "Auto change". Hence, the default remain using Auto (lines current scheme remain the same as FXSSI) but it will based on luminous of the background color. The formula is at here >> https://stackoverflow.com/questions/596216/formula-to-determine-perceived-brightness-of-rgb-color.
2. If background is dark (black etc.) it will use Light Colour scheme
3. If background is bright (white etc.) it will use Dark Colour scheme
5. Server time offset (do double check if is correct on any MT4 broker)

Others settings should remain the same of the source. Design, aesthetic, default value, and description should all the same.

Clean and Readable source code is needed by the end of project.

Experience & Responsive developer is highly recommended. Please do send me screenshot of past projects you completed so I know more about your experience.
