Multiple staggered entries using an ATM. Which Platform can do it?

I've got a trend-following strategy that averages down into pullbacks.

For instance, say the market is trending up, makes a high at 1910, and begins to pullback.

I need a platform that will allow me to:

- on a single click, enter several limit buy orders below the market. For example, at a single click or hot-key, enter limit buy orders at 1909, 1908, 1907, 1906 and 1905
- employ a universal stop loss for all orders.
- allow that universal stop loss to be visually modified.
- allow all trades to be closed at once (close all function).


Seems pretty simple to me, but I don't see this functionality in MC or Ninja without coding an automated strategy.

And if the strategy is automated, thats fine. But the entry logic is discretionary. More specifically, the trigger criteria I want to be kept discretionary. When to submit all the limit orders for entry, and when to take them all off.

Which platforms are best for this?
