MT4 Exper Advisor based on PSAR

1. I need Expert Advisor for MetaTrader4. 
2. it must be work with 24/5 ECNaccounts. 
3. it is able to be used in vps system
4. it can load to any chart(eur/usd, xauusd...) and timeframe(m5, m15, m30, h1, h4..)
5. i can determine trading days and hours. (example: i can set that trading time ; monday-thursday 06:00-21:00 (GMT+2 )or another day and time.)
6. it close all open positions when scheduled closing day and time.
7. i can determine stop loss pips and take profit pips. (example: xauusd price 1588.50 . my stop loss 1588.25 . my take profit 1588.73. i will determine stoploss: 25 , takeprofit:  23)
8. i can determine trading Lot. (0.01-100)
9. my goal is to start trading as the parabolic sar indicators(0.02 , 0.2) change. i showed in the picture where to start trading.
10. when i started ea robot any day or time, firstly it will not start trading until psar trend changes. because my goal is to start trading with the first psar trend changing bar.
11. If the trading is not closed until the changing of the psar trend, it will close the old one(close buy/sell, profit or loss situation does not matter) and start the new one(start buy/sell according to new situation. 
12. When the parabolic SAR trend changes, the robot will only one(1) buy or sell trading.
13. The lot of the trade after the stop loss occurs should be the amount I set (lot after stoploss). later trades will be the same as I first set. This is an important point. for example; Let me imagine that I prepared the robot for the working that - 0.01 lot , stoploss 20 pips, takeprofit 50 pips, lot after stoploss 0.1 lot - and robot start...first starting, it buy/sell and take profit 50 pips (0.01 lot)... second it buy/sell and stoploss occurs 20 pips (0.01 lot)... third it start trading with the lot that I set (0.1 lot). the name of this is “lot after stop loss”... fourth it buy/sell and take profit 20 pips (0.01 lot) and fifth, sixth, seventh.....(continuation 0.01 lot, until stop loss occurs).
14. I also want to have software codes and all right reserved.
15. before purchase we need demo for backtest
