[Calculation Tool Gift] Fixed lot is dangerous. This is the lot calculation method used by the winners
I assert this! If you fixed lot size, you’ll never win for life.
“I think fixed lots will be fine until I get used to it.”
“I don’t really understand lot sizes, so I’ll leave it for later.”
With 20 years of FX experience, I’ve talked with hundreds of traders.
Almost everyone who keeps losing had fixed lot sizes.
When you use fixed lot sizes,
“Unnoticed trades with small gains and large losses are created.”
that is the mechanism.
■ The true nature of the “steadily winning then crashing” caused by fixed lots
But in reality, risk varies each time due to three factors.
【① Risk changes with the stop-loss width】
Comparing the same 0.1 lot, USD/JPY (1 pip ≈ 100 yen)—
・Stop loss 10 pips → loss about 1,000 yen
・Stop loss 30 pips → loss about 3,000 yen
・Stop loss 100 pips → loss about 10,000 yen
Even with the same lot size, the loss amount can vary by up to 10 times.
In scalping you close at 10 pips, but in swing trading you might target 100 pips.
The same “0.1 lot” can become a trade with 10 times the risk.
