Quote from funky:
[Seykota] says that while transaction costs stay the same, the profit is smaller with shorter trends. he then concludes that it is more profitable to trade longer timeframes, because it is RISKIER to trade short term trends. i don't know about you, but I've seen that the shorter the timeframe, the less risk is involved...for me at least. while the profit is smaller with shorter trends, there are MORE of them. this more than offsets the profit/transaction ratio. the ability to consistently compound your money is being overlooked here, which makes short term trend following much more profitable in the end. but, hey, to each his own -- he's the market wizard and i'm the young grasshopper.
I think Seykota reasons that daytrading/very short term trades are riskier exactly because of the reasons you give. There are more trades the shorter term trader takes, and there's a risk with every trade, so there's naturally overall more risk.
Also, short-term traders have to find the next trade every day/ every moment because they're not committed in longer term trends. More work!
Every penny of profit is more critical when you're in for a short term, as opposed to a much longer term, especially given that you can reach a BE point and have a reduced risk trade you can ride the rest of the however long the trend goes. Less pressure.
And while the argument for the effects of short term compounding sounds as if it would be a benefit, compounding does work both ways, for you and against you, and short term losses can compound and erode that much faster in short term trades. I guess that falls under "more risk" as well.
Someone else wrote about Seykota having a knack for predicting tops/bottoms. I don't see where he does that. He writes about being reactive and not predictive, and further, he writes about putting on trades knowing already at what price point he'll stop out if the trade goes wrong, which seems to indicate that there is no attempt on his part to "call a top". Just to "call a broker" if he needs to get out.
I think his "secrets", if you want to call them secrets, is that, simpler is better; the old methods have stood up through time, the markets do not change (as regards trends); long term trends reward well, don't chase after the last eighth; you need not be emotional if you can trust your system, manage risk and the profits will follow.
