Are you going to double the account ever ten percent? Also, the live account is then 40k. So it goes up 4 times immediately upon passing. Buy it or don't - doesn't effect my bottom line either way, just better than trying to get ten then five percent for a smaller account. Ten percent in a month is ridiculous. There is also a 6 month time limit, makes a difference as well, so there is that. Also, for what it is worth, the accounts show up as live accounts on Forex trackers. (Although I have heard there is a way to fool them.)
From what I see on FTMO it is 10% over 4 months not 1 month and the only other requirement seems to be that 2 of the 4 months need to be profitable. So if you have their max acct size -- $100,000 - that is initially getting a $10,000 profit over 4 months here is the text on their website as of today - https://ftmo.com/en/scaling-plan/ "Capital increments on the FTMO account take place in four-month cycles. For a capital increase, the trader has to gain at least 10 added percent points in four consecutive months (i.e., the average of at least 2.5% gain per month). At the same time, at least 2 of these 4 months need to be profitable. If the trader fulfils this, the initial capital of the FTMO account will be increased by 25%. Along with that, the basis for the calculation of loss limits will change accordingly and risk parameters will be loosened. After another 4 months, if the trader again satisfies the conditions of appreciation and the ratio of profitable months, he/she will gain the eligibility of further increase of the capital by 25% of the Initial Capital of the FTMO account. Increments of capital have no ceiling."
