EA based on Stochastic

Please read the requirements carefully and reply with which parts can be done, can be done for this price range or for a higher price. We can negotiate from there..

Hi, I need an EA based on the Stochastic oscillator indicator with following features,

1. Stochastic oscillator indicator settings: 5,3,3 and levels 20, 80.

2. Place orders whenever there is a crossover of stochastic above or below the levels.

3. Wait for the stochastic to go below or above the levels, then the crossover of value and signal, and then close of a bar in the intended direction.

4. Prefixed spread within which trades can be opened.

5. Take profit and stop loss based on ATR 14.

6. Option to close half of the lot for a fixed take profit.

7. Option to set break even and trailing stop increments.

8. Visual and audible alerts when and where a trade is opened on the chart.

9. Time frames to include 5 m, 15 m and 30 m.

10. Preload the required indicators and templates on the chart.

11. Initial delay of preset number of bars or minutes before a trade can be taken. Same period of waiting at the start of every day when run continuously for days together. 

12. When attached to multiple charts, a trade can be opened only when no other chart has an open trade.

13. Option to set daily, weekly and monthly targets.

14. Money management features such as lot size calculation or fixed lot whichever is smaller.

15. Option to choose London, New York or Tokyo sessions or overlaps or predefined start and end timings.

16. Option to stay away from news timings.

17. Coding should be understandable, adequately commented and follow professional best practices.

18. Complete source code, with all classes and include files, if any, most important avoid Dll's.
