Quote from trade-ya1:
I trade the futures but not in the pits and often not on Globex. Many of those Globex prints are bullshit. I had a stop to sell futures at 1.2180 and the low was 1.2171. I DID NOT get filled on my sell stop. The reason is that I work them "EFP" or Exchange for Physical with a dealer desk. That means that I am really doing a cash trade and the dealer is converting it into a futures contract for me. The cash market did not trade anywhere near the level that 1.2171 or 1.2180 would have been done and as a result, I was not filled on my stops. The futures market has an exact relationship to the cash market. Currently, the spread between cash EUR and the Dec. futures is 8.5 ticks. There is not enough liquidity for me to do my size generally on Globex or on the floor. Sometimes, when the markets are quiet and I am initiating new positions, I will use Globex.
