Pending order script

Hello!

I need a script that will open 29 sell pending orders in the following manner:

First sell 0.02 lots, then place a sell limit order 10 pips higher 0.02 lots, and another one 10 pips higher than the second one 0.02 lots.

After the first 3 orders the lot size increase by 0.01, so another 3 sell limit orders at 10 pips distance from each other 0.03 lots, then another 3 orders 0.04 lots and so on until it makes 30 orders.

So basically the script opens a sell of 0.02 lots, then makes a grid of 29 sell limit orders, 10 pips distance from each other, increasing the lot size every 3 orders by 0.01 lots.

I need the same script for buy.

I will use these scripts on MT4 and I require the source code in case I need to change the lot size after some time.

Looking forward to your offers.
