Sorry. The numbers I simply posted are incorrect. Having a 10tp/10sl you are simply breaking even once you double the lot dimensions. You would have to either
A- Shrink the SL
B- Increase the TP
c- Increase the lot multiplier

Heres an illuion for our visual learners!
In this SL is 10 however, the TP is 20

Market @ 1.8130 buy 1 lot 20tp/10sl
market @ 1.8120 sell 2 lots 20tp/10sl
market @ 1.8130 buy 4 lots 20tp/10sl
market @ 1.8120 sell 8 lots 20tp/10sl
market @ 1.8130 buy 16 lots 20tp/10sl

Finally the market stops ranging
market moved 30 pips south.

Market @ 1.8120 sell 32 lots 20tp/10sl
market @ 1.8100 close place

Order 1 10 pip SL * 1 lot -10
order 2 10 pip SL * 2 lots -20
order 3 10 pip SL 10 4 lots -40
order 4 10 pip SL * 8 lots -80
order 5 10 pip SL * 16 lots -160
order 6 20 pip TP * 32 lots 640
