需要一个按时间段进行交易的 EA (Need an EA that trades by time period)

I have developed a spread sheet that keeps track of ½ hr. price movements starting from 1/3/07. It separates and then totals the price movement for each period.
Example: Between 7 AM and 7:30 AM CDT the GBP/USD has gained 459 Pips.
I then scan the totals and try to find ½ hr. time periods that when put together will give the maximum gain.
Example: Between 7 AM and 11:30 AM the GBP/USD has gained 1829 Pips.
I then count the number of trades it would have taken during this period multiplied by the spread and check to see if a profit can be made.
Example: On the GBP/USD 188 trades at 4 pip spread = 752 pips.
1829-752=1077 pip gain.
After 6 months of data I kept track of the trades it would have made for the following month and using a spread sheet determined what stop limit was needed to maximize profit.
For the past 30 days I have papers traded GBP/USD, EUR/USD, and EUR/JPY USD/JPY using this method and show a 1600 pip gain.
I would like to get an EA written that would allow me to enter the time for Entry and Exit and it would need lot size and a stop limit.
