1. This indicator does a simple relative estimation of strengths and weaknesses of different individual currencies and then pair up the weak with strong ones and displays the data on the chart, which I will explain below step by step. 
2. Find the position of the price (if it is above or below 200SMA close) for all 28 forex pairs.  Suppose for EURUSD in D1 time frame, let us say the last D1 candle which closed at 5PM EST (end of Forex day) is trading below 200SMA.  You give in this case a DOWN arrow for EUR and an UP arrow for USD.  If in the case, price happens to be crossing the 200SMA from one side to the other, then look for the last D1 candle’s price’s close above or below 200SMA.  If it closed below 200SMA, you give EUR a DOWN arrow to EUR and an UP arrow for USD.  Similarly, you repeat this process for the remaining 27 pairs in D1 time frame.  Once you come up with these arrows, then pair up those DOWN arrow currencies with UP arrow currencies ONLY.  Do not pair up currencies which have arrows in the same direction.  You will come up with about 15-16 pairs in this D1 time frame, after pairing up.  
3. Repeat this process in all time frames from M1 to MN time frames. 
4. This indicator then should display in all 28 pair charts a rectangular table with time frames in top row and below it in the 2nd row, the UP and DOWN arrows, which you came up at the end of Step 1 above.  
5. We should have the option for visualization of this table in whichever time frame we want.
6. We should have the option to change from one MA to another MA like a different number MA (say from 200SMA to 100SMA) and change the type of MA from SMA to EMA (say from 200SMA to 200EMA).
7. Option for placing the table anywhere on the chart.
8. We should have the option for testing the historical candles in the past.  So we should have the calendar with starting date.  If I put Jan 15 2016 in the calendar, I should have the above table displayed (that you came up in Step 3 above) with the above data for all time frames form M1 to MN time frame closed at the end of January 14, 2016.  This calendar allows for back testing the strength and weaknesses of currencies anytime in the past.
9. You should only work with MT4 platforms whose D1 candle starts at 5PM EST and offer only 5 D1 candles in one week.  I work with FXCM USA.  You can download their platform on their FXCM.com web site.
10. I am willing to pay $20 for this indicator and time to complete is this weekend.   The main thing I look for in you is flexibility.  You should be flexible enough to make changes in the indicator that I ask you from time to time to make it more user friendly and more informative in the prediction of strengths and weaknesses of currencies.   If these improvements merit additional money to you, we can determine that thing at that time.  I do this manually now and it is pretty simple, but does take time to come up with the final rectangular table.  So, I suggest you do this table for one day in the past (let us say you produce this table on the chart for February 25, 2016) and I can guide you to let you know if you are doing it correct or need to make certain corrections.  Ple. ask me any questions you may have before you start this work.
