I need an expert adviser simple grid strategy

I need an expert adviser simple grid strategy.

I opened or will open a trade manually, Order No 1. EA need to put 3 pending order on a specific pair.

Trade direction= Same as Order no 1

Grid size 3 = number of pending order 3

grid spacing 45 pips = difference between each pending order 45 pips

grid multiplier 25%,50%,75% = lot size according to order no 1 (order 2=25% of order no 1, order 3=50% of order no 1 , order 4=75% of order no 1)

Take Profit and Stop Loss for pending order= order no 1 Take Profit and Stop Loss

Maximum spread during pending order execution is 3-10 (customise pips set my me) pips, if spread is more it will cancel only this order.

Cancel all pending order when order no 1 hit Take Profit 

The EA can be run any PC without any limitation and file format must be .ex4

Ea will use on 5 decimal broker

Ea must have custom comment option

EA need to place pending order, order no 4, after 45 pips from order no 3, lot size 75% of order no 1, same direction to order no 1, same Take Profit and Stop Loss of order no 1. If any of the order hit Take Profit before this order opens then this order have to cancel 

Order no 1 Take Profit and Stop Loss can changed time to time, rest 3 order Take Profit and Stop Loss also have to synchronisation with order no 1 until the order no 1 hit Take Profit or Stop Loss
