Could you please show an example on how to use this?

Thank you so much, i appreciate it!

How do you completely decline the trade?

Say in case there was someone who have declined like 3 times, and i just want to cancel this trade.
How do i make the process stop? Because i tried decline trade, but it still kept trading.

Best regards

Do you mean like not trade that person again? If so this will have to be done in your own script logic.

An example would be to add that player to a blacklist after he has declined the trade or keep track of how many times that player has declined the trade and if it exceeds a certain threshold add them to the blacklist to not be traded again.

Example Code Without Threshold (Untested):

Spoiler

private Trader trader;
private ArrayList<String> blackListedNames = new ArrayList<>();

@Override
public void onStart() throws InterruptedException {
    trader = new Trader(this);
}

@Override
public int onLoop() throws InterruptedException {

    String playerName = "PlayerName";

    if (!blackListedNames.contains(playerName) && trader.trade(playerName)) {
        if (trader.offerItem("Iron arrow", 100)) {
            if (trader.acceptTrade(true)) {
                if (trader.itemTradedWithLeftOverItemAmount("Iron arrow", 200, 100)) {
                    log("Item Successfully Traded!");
                } else {
                    log("Trade Unsuccessful!");
                    blackListedNames.add(playerName);
                }
            }
        }
    } else {
        //Set the player name to a different player name.
    }

    return random(800, 3000);
}

Example Code With Threshold (Untested):

Spoiler

private Trader trader;
private HashMap<String, Integer> playerTradeHistory = new HashMap<>();
private int threshold = 3;

@Override
public void onStart() throws InterruptedException {
    trader = new Trader(this);
}

@Override
public int onLoop() throws InterruptedException {

    String playerName = "PlayerName";

    if (playerTradeHistory.containsKey(playerName) && playerTradeHistory.get(playerName) < threshold && trader.trade(playerName)
            || !playerTradeHistory.containsKey(playerName) && trader.trade(playerName)) {
        if (trader.offerItem("Iron arrow", 100)) {
            if (trader.acceptTrade(true)) {
                if (trader.itemTradedWithLeftOverItemAmount("Iron arrow", 200, 100)) {
                    log("Item Successfully Traded!");
                    //This will remove the player if they had declined some trades but finally accepted one of them.
                    if(playerTradeHistory.containsKey(playerName))
                        playerTradeHistory.remove(playerName);
                } else {
                    log("Trade Unsuccessful!");
                    if (playerTradeHistory.containsKey(playerName)) {
                        int oldValue = playerTradeHistory.get(playerName);
                        playerTradeHistory.replace(playerName, oldValue, oldValue + 1);
                    } else {
                        playerTradeHistory.put(playerName, 1);
                    }
                }
            }
        }
    } else {
        //Set the player name to a different player name.
    }

    return random(800, 3000);
}

tried to use this and whenever the methods were called it would spam NPEs and cause my client to crash. I know this is old, just wanted to let other people who may want to use this know.

[Wacky Jacky]

Can confirm it works, only if on the second trading screen, the player who gets offered the trade accepts before the bot/script running player presses accept, it will fail and indeed give a NPE. 
 

this is because it detects the text on top, when the normal player accepts, the bot gets to see “other player has accepted” and tries to click that instead of the accept trade button. 
 

lovely snippet thanks.

Nice, I might incorporate this into my botfarm scripts
