* A value of up to 50k: there is a 10 second delay before the balloons drop.
* 50k - 150k: there is a 1 minute delay before the balloons drop. The Falador bankers and Party Room barmaids will announce that a party is happening.
* 150k - 1 million: there is a 5 minute delay before the balloons drop. The Falador men and women, bankers and Party Room barmaids will announce that a party is happening.
* 1 million+ : there is a 10 minute delay before the balloons drop. The Falador men and women, bankers and Party Room barmaids will announce that a party is happening. Nearly all the bankers across RuneScape will also announce that a party is happening, and will offer free teleports to the Party Room.
So if you trade 50k at a time you're almost perfectly safe. No announcements and if you're doing this multiple times, the chances that you lose 50k (which is only a small proportion of the total amount you will transfer ultimately) are much less and so is the risk.
