Here is a strategy and it's free....
Seems to work quite well on YM but careful not to get your fingers burnt.
1. Just before the open make a nice cup of tea - I find PG Tips as good as any.
2. Take a fresh packet of Rich Tea biscuits and remove one and keep at the ready.
3. Wait for the first minute candle to form then dunk the biscuit in the tea about halfway and hold in the hot liquid for approx 3 seconds.
4. Gently lift the biscuit from the tea and hold above the cup.
5. This is the important bit: If the dunked half falls back into the cup then SHORT at market, if it remains intact then go LONG. Try and time step no. 5 to coincide with the third candle.
6. Now make another fresh cup off tea, sit back and watch and exit on the completion of the 8 minute candle.
7. If successful then repeat steps 3 - 5 again as many times as you like or until you run out of biscuits.
If not successful try using chocolate digestives....
The above strategy is intended for educational purposes only and trading futures with scalding hot liquids can result in a nasty accident.
