Grandexchange buy a raw shrimp process.

[demarco 0]

GrandExchange twindow = getGrandExchange();

twindow.openBuyScreen(1);
twindow.searchItem("Raw shrimps");
twindow.addBuyItem("Raw shrimps");
twindow.setPrice(100);
twindow.setQuantity(1);
twindow.confirm();

Starting on the grandexchange screen, i want to buy 1 shrimp for 100gp.

However the code above clicks on a trade window, and doesn't search for raw shrimp. It just starts adjusting the quantity and price. Am I missing a step?

Each of these return boolean value, try using these inside an AbstractScript.sleepUntill();
Also you do not need to use getGrandExchange().searchItem(), before using getGrandExchange().addBuyItem(itemName), because addBuyItem will do that for you.
So your code could look like this:

Main.sleepUntil(() -> getGrandExchange().open(), 5000);
Main.sleepUntil(() -> getGrandExchange().openBuyScreen(1), 5000);
Main.sleepUntil(() -> getGrandExchange().addBuyItem("Raw shrimps"), 5000);
