The New York time between 3:00 PM EST to 7:00 PM EST is best suited for scalping with the counter trend strategy. Off hours between 3:00 PM and 7:00 PM EST is when all the world banks are closed. The U.S. banks are closing their doors and the Asian banks have not yet opened. This is a great time to scalp the market using a counter-trend strategy, because no larger banks are moving money (i.e. the markets) at that time. Just as with the London close, there is no set way in which the New York afternoon market plays out. On more active days where prices have moved significantly, the lower liquidity can cause additional outsized price movements. So traders just need to be aware that lower liquidity conditions tend to prevail and adapt accordingly.
