What is an open scream?

Open cry is a system by which financial traders conclude agreements through personal contact. This is contrary to electronic business systems carried out through computer links that are more common on large financial exchanges. The open scream consists of voice communication and a gesture of hands. It somewhat resembles communication used in some countries of bookmakers who work on the racecourse. The numbers one to five are transmitted by pointing the hand up and raising the number of fingers. The numbers six to 10 are done by pointing the hand to the side, with one extended finger corresponding to the number of six, two fingers corresponding to the number seven up to all five corresponding 10. Finger or fingers touching the chin show that the number is in the units, so one finger means simply one. Fingers to the head means that the numbers are 10s, so three fingers means 30. The numbers in hundreds first touchforeheads of a closed fist.

There are several other commands that can be mediated. A person who shows his hands with the palms facing each other together shows an offer to buy while someone with palms pointing away shows the offer for sale. They match the position of the hand if someone physically attracted something together or pushed them away. There are also individual gestures corresponding to each month of the year for the closure of trades that have expiration data, such as futures contract.

The main advantage of open cries is that traders can read body language and facial expressions of other traders. This can help them negotiate from a stronger position. The main disadvantages are that traders are more susceptible to flu from individual traders and that they will have less information in comparison with traders working from the computer system.

Hand gestures used in open outrage are somewhat belowThey intend to use bookmakers on Racetracks. This communication is known as TIC-TAC. The big difference is that bookmakers use TIC-TAC to cover information so that they can give details about which horses receive many betting without sharing this information with opponents. Unlike financial traders, bookmakers tend to develop their own gestures and can even intentionally suggest that they are misleading for anyone who sees them.
