making a profit then blowing it.........

[fatsam]

I think a classic mistake to make is when running up profits from a staking plan you are comfortbale with you then suddenly change stake sizes, and amounts traded.
If by putting chunks of say £50 through the markets has given you a good profit, why not keep using that figure to generate constant profits until you are comfortable with a new amount to trade.
Psychologically its easier to deal with than suddenly increasing your stakes and thus tick size figures and over reacting to a loss that previously you would have traded out of or ditched.
Small tick values against you are far easier to deal with than big ticks. But essentially a tick is a tick , its only the new value increase per tick that has the brain confused or reacting disproportionaly.
you dont run a marathon if you used to 100 or 200metres. Ask Bolt, I'll be suprised if he trains over any distance greater than 400m.
