I need an EA that place pending trading orders (STOP and LIMIT ORDER) based on price (no indicators)

Draw grid on MT4  chart at 25pips intervals and divide each grid into two i.e at 12.5pips interval.

Place pending STOP orders on all grids at same lot size [make provision for lot size adjustment] up to 28 grid levels on either side of market price.

In placing pending orders,place buy stop orders above the current market price and sell stop orders below the current market price.

Each pending orders must have same stop loss and take profit values [ Create provision for inputing stop loss and take profit ]

Once a pending order is triggered and the next order below or above the first order is also triggered,move stop loss of the 1st order to break even i.e move stop loss to its entry price.

chart me up for more explanation
