"However - I feel it is nearly impossible to make decent money or even appreciate decent performance when you're trading 1 lot."
however, how you FEEL is not consistent with how trading and traders minds work.
i have mentored many futures traders, and i can tell you it is an exceptionally rare trader that would not feel VERY stressed with 10 lots without a LOT of experience. and stress leads to emotional trading, revenge trading, poor decisionmaking, etc.
it is also factually incorrect to say you can't get decent performance with one lot.
i'm not saying you are going to make a good living doing 1 lot, but no inexperienced trader should ever start out trading having to make a living from it.
the VAST majority of traders are well served with starting out 1 to 2 lots (imo after papertrading and/or trading DIA as a YM proxy for several months) and not exceeding 2 lots for AT LEAST another 6 months to a year. at least
better to have a 20k account and trade 2 lots, and put your other money in other stuff NOT FUTURES, than start trading 10 lots
that's absurd and nobody who is responsible would recommend 10 lots to a beginner
a 10 pt dow stop with one contract is $55 of risk (assuming $5 round trip and no slippage (i rarely get slippage, but assume two ticks slippage in a bad market, that's $65 of risk)
most beginning traders can trade that comfortable.
if you play high probability plays, there is no reason why you can't make 20 YM pts a day, which is a nice $100 for one contract, which is quite doable.
that's not gonna make you rich, but it's a good start in learning how to trade.
and assume 3 losses in a row with a 10 pt stop AND slippage, you are looking at under $200 of loss for the day, which is not gonna break you or emotionally disturb most traders
you are ultimately trading against yourself and trading 10 lots is an absurd recommendation for anybody but a seasoned trader
