Fast internet connections

If you invest in the stock market, have a pension or life insurance and have never heard of High Frequency Trading then it is extremely likely you have lost money to this practise.
High Frequency Trading is essentially the use of computer programs known as algorithms and high speed internet connections to find out what stock trade is being made and to then buy or sell that stock before that trade can be made, taking an instant commission from the price jump. It’s like invisible Gazumping only much faster and you only get in the middle of the trade for a millisecond.
