Quote from Zr1Trader:
If I had to go back to the first day I'd tell myself not to over trade or cross the spread all the time,churning the account in small ranges. Trade products with good range in relation to spread and commission.
In other words don't have a 10 tick tgt and 10 tick stop .... with a 1 tick spread that is 10% of the trade going to the house not including commission. Don't be a dumby and churn your account making only your broker money.
Unless one has a very robust method on smaller timeframes it is tough to beat costs like the high volume or exchange members and be able to compete on that level. Broaden the timeframe or range a bit is what I'd say.
Keep costs of doing business low.
