Back testing for nifty strategy and then build robot

1. looking for a EA that opens on a Pivot or reversal.

2. once opening position happens buy or sell it then also opens a buy and sell stop 400 points from opening position.

main strategy: opens buy or sell once 50 point movement has happened it then opens a trail stop that follows position 50 points behind current price but opens after 50 points. Closes position when it drops back to the trail profit.

2nd part of strategy if it goes against original opening position. (opened buy but then turns to Bear or other way around) 

then a martingale Grid strategy format of every 100 points another position opens (opening-0.01 - 0.02 - 0.03)

for 3 steps only as the 4th step would hit the buy/sell limit from the original opening (2) which should open a 4th position in the way of the current trend.

thats it really.. 

if this is even possible to make it would be much apricated as i think it would be a winning strategy as a EA as i use it in manual trading with great success
