In TDO version 9.2 I have enhanced the alert and notifications to work better with the MT4 system tester
.
Note:
I didn't make any changes to TDO's basic formula. It is still the same.
I didn't make any changes in indicator parameters or buffers.

Fixed a small bug in the de-initialization function, that used to cause the symbols switch tool not to work properly.

Note:
I didn't make any changes on TDO basic formula. It is still the same.
I didn't make any changes in indicator parameters or buffers.

1. Enhanced TDO code to be much more faster.
2. Decreased indicator buffers from ten to six.

4. Added a background to the Martingale Panel.
5. Added the option to show channels as shaded area or as lines.
6. Enhanced the messages code.
7. Enhanced the colors list.

What is new in TDO user to version 8.0:

1- You can show or hide TDO Panel and Buttons by clicking on Shift + A / D.
2- You can switch between four beautiful and well-designed Color Lists. Or you can use your own color list by choosing the (Do Nothing) choice.
3- You can send Mobile Notification or emails and if anything gets wrong you will receive a note in the terminal's journal.
4- Indicator objects now change their size automatically by depending on screen resolution.
5- Made inputs much more user friendly.
6- Made a revision to the code to make sure that there are no bugs.

You can now increase/decrease all buttons font size. This new feature is good for:

1. Those who use brokers with nonstandard symbols list. (ex: EURUSDecn, GBPUSDecn,...etc).

2. Those who want to enlarge their screen resolution through the windows (Customize Sizing Options).
