I think it will be very difficult to trade EURUSD 5-min charts using Bob's method. TonyIommich once compiled statistics of number of trades during the 6-month period in Bob's second book. There weren't enough setup. Earlier this year (Week 14) Bob provided 5-min charts for three pairs (EURUSD, USDJPY and AUDUSD). The opportunities were scarce.
The book itself is worth reading. It helped me better understand the principles he laid out in his previous book, FPAS. In February I started trading the above mentioned three pairs using 200-tick charts (there is a whole chapter about trading in low volatility environment in UPA, the second book). Then starting in May I switched back to 70-tick for EURUSD but kept the 200-tick charts for the other two pairs. The 200-tick charts are very similar to the 70-tick charts, except that Bob used angular lines more often.
My opinion is if you know FPAS really well you don't need to buy UPA. If you don't, or if you trade other instrument and prefer the 5-minute timeframe, it can be helpful (ask TonyIommich who trades ES, 5-min charts). If you do trade forex and feel 70-tick is too fast, then you may try 200-tick as I did, and when you feel more comfortable with the speed you can come back to 70-tick.
