Drawdown isn't a data point of primary concern over the long term.
Consider this, if you have a DD of 10% and then one day a trade goes bad, and another and another, and those 3 bad trades go against the account, and you end up with 60% DD because of one day of your trades. But prior to that, you had a great DD.
If we take into consideration when, why, and how the DD occurred, then it's a more realistic analysis of the account.
If however, the strategy being used for trading regularly uses 60% DD against the account, then it's a serious problem for the investor. It means that they aren't using safe money management, and they are probably trading with a higher leverage than they should be.
There is a BIG difference when trading 0.5 lot size on a $100.00 account, and trading 0.5 lot size on a $100,000.00 account.
If it looks too good to be true, it's probably a scam! Let the buyer beware.
