I am searching for something like from a Russian fairytale: "not a mouse, not a frog, but unknown creature" (it is my trasnlation, that's why so ugly)

Hi, I am serching for something (a robot, a program, an access, a special broker service, whetever), which would allow to: a) conducting very very few deals a day (1-2-3) condut them at the highest speed; easily place and cancel the orders, cancel all order using one button only, etc; c) save money :-). As conducting as few as 1-2 deals a day I cnnot afford expensive exchange direct access for example, and I need some more budget option. Thanks a lot! Regards, Kloto
