Modify a grid EA with custom indicator

I have a grid martingale EA and need a good programmer to modify the entry condition 

The EA currently open order based on price border indicator, if the price go above the upper line then the EA open sell order in the new open candle , if go below the lower line then open buy order and then following with grid and martingale order. Now I want to modify it as following: 

1. When price go below blue line of Priceborder indicator, then buy when the Super Trend Indicator turn from red to green and the Laguerre indicator is below 0.15. At the time of opening buy order the price may be above the blue line of Priceborder Indicator. Exit buy order when hit TP or Stop Loss. 

2. When price go above the red line of Priceborder indicator, then sell when  the Super Trend Indicator turn from green to red and the Laguerre indicator is above 0.85. At the time of opening sell order the price may be below red line of Priceborder Indicator. Exit sell order when hit TP or Stop Loss. 

3. Modify Grid Function:

if the input "Step Size in Pips" > 0 then open grid order base on step size. The same as current EA, you don't need to change any thing. 

If the input "Step Size in Pips" = 0 then open new order with increased lot size whenever the price go opposite direction of current order and the condition for buy or sell order is met (condition is describe in 1 and 2 above).
