How it works
You start with equity of 100 in your account currency and pick a leverage between 1× and 50×. On each tick the price moves at random by up to about 2% up or down, and your equity moves by roughly that change times your leverage: at 10×, a 1% move changes your equity by about 10%. If equity falls to 5 or less, the position is liquidated and the game ends. Get through all 30 ticks and you have survived. The thin horizontal line marks your starting equity of 100.
On a real margin account, a price move of about 1 ÷ leverage against you is enough to wipe out your equity: roughly 10% at 10×, 2% at 50×. Brokers and exchanges usually liquidate even earlier, at the maintenance margin, and fees, funding costs and price gaps make it worse. One game says little. Play several times at the same setting and look at how often it ends in liquidation; that frequency, not a single lucky run, is the lesson.
