Victor Adair, author of The Trading Desk Notes, began trading penny mining shares while attending the University of Victoria in 1970.

Between 1977 and his retirement from the brokerage business in 2020 Victor held a number of trading, analytical and senior management roles in Canada and the USA. Victor started writing market analysis in the late 1970’s and became a widely followed currency analyst in 1983. He started doing frequent media interviews in the early 1980’s and started speaking at financial conferences in the 1990’s. He actively trades his own accounts from The Trading Desk on Vancouver Island. His personal website is

You can never have enough on when you’re right.


I just closed out some “risk off” positions (short stocks, Euro and gold) that I’ve had on for most of the past 2 weeks. I caught some good moves, especially short stocks, and I decided it was time to take profits. It was one of my better 2 week periods of the year…in terms of my P+L…but it wasn’t very exciting…actually it felt pretty “routine.” I saw what looked like good trade setups, I put on some trades, put protective stops in the market, lowered the stops as the markets dropped and eventually cancelled the stops and covered my shorts at the market. A pretty routine process.


The whole process would have been a LOT more exciting if I’d been trading HUGE size…but I wasn’t.


I remember visiting the Chicago floors back in the 1970’s / 1980’s. I must have been there 100 times and it was always a HUGE BUZZ. I’d be dressed in a business suit while everybody else was wearing trading jackets…so I stood out like a sore thumb and I “just absolutely knew” that everybody thought I was a pigeon.


The floor could be relatively quiet and then suddenly “ERUPT” with hundreds of people screaming and frantically waving their arms…desperately trying to get a trade done.


Back in those days commodity trading was all about trying to turn 10 Grand into a million…as quickly as possible. Everybody knew somebody who had done it…and everybody knew somebody who busted out trying.


In 1983/4 when I was the global currency analyst at Conti I would give a breathless 5 minute currency report over the “hoot and holler” private phone system that connected all of our North American and European offices and then use the same phone system to place orders for my own account…knowing that 500 brokers could hear me entering my orders.


I ran my account from 10 Grand to 30 Grand that year…using WAY more leverage than I would ever dream of using today…but as the boys on the floor used to say, “You can never have enough on when you’re right!”


But when you use too much leverage…sooner or later you’re going to get caught. Sooner or later you’re going to look at your screen and just go numb with disbelief. I’ve been there and I wouldn’t wish it on anybody.


I wrote a piece under the Trading Principles headline the other day about finding a way to trade that suits you. Finding your way has many parts but one of the most important things you have to find is what suits you in terms of sizing. My friend Peter Brandt ( says that if you’re willing to lose more than 5% of your trading capital on any one trade then sooner or later you’ll go broke. He generally limits his losses on any one trade to less than 1% of his trading capital.


I size my trades these days so that if they’re a loss it doesn’t matter and if they’re a winner that’s nice…not fantastic…not life altering…just nice…and then I move on to the next trade. A trade is just a trade.


I know I’m going to increase my sizing one of these days…just to crank it up a bit..but I’ll need to feel real solid about my process before I do that. I’m not trying to prove anything to anybody. I’m just a guy trying to do a good job, knowing that more than half my trades are probably going to lose money.
