Create EA based on renko chart, 
When new brick is created EA should send below values to web request
1. Date/ Time
2. Symbol
3. Open 
4. Close
5. High
6. Low
7. DC - Upper 
8. DC - Middle 
9. DC - Average 
10. MACD
11. MACD Signal
12. Stoch
13. Stoch Signal
14. Moving Average of scilator (OSMA)
15. CCI (Commodity Channel Index)
16. AO (Awesome Oscillator)

DC,MACD,Stoch,OSMA,CCI and AO will be added manually to renko chart, each will have their own settings (no need to manage their settings from EA) Before start of EA, i will manually add all these indicators and then EA will just read values and send to web request.

EA should display countdown clocks for 10 major markets 
Example  
NYSE 02:33:14 Hours until open or 03:44:18 Hours until close
In paramaters, i can define exchange name, opening time and closing time, basically, you can set a reference time zone and then based on that i can select opening and closing hours.

Add paramater web request address for data 

Send keep alive signal
Add three paramaters in settings 
Keep alive name
Keep alive address
Keep live frequency

if i add frequency 1 second, then every 1 second EA will send keep alive name to the keep alive server at teh defined address, this is to alert when EA has stopped working. 

All the code should be very clear and documented and highly optimized.
