Lesson 4 | How Is Drawdown Calculated? Understand Your Account’s Actual Room for Losses

Build the Rules into Your Trading Plan

After choosing an evaluation format, build its rules into your trading plan: Does this account’s loss allowance fit your method?

Two US$100,000 accounts may have different floors under static or trailing drawdown. Reaching the profit target may also leave consistency and minimum-day requirements to meet.

This lesson calculates each rule to show how it affects trading.

The examples use a US$100,000 account. Each scenario is separate and does not represent any firm’s current offering.

Give Each Trade Its Own Risk Budget

Suppose you decide to risk 1%, or US$1,000, on each trade idea.

For a planned gold long, identify the entry and stop-loss levels, then calculate the position size for an expected US$1,000 loss at the stop.

Here, 1% is the planned loss if the stop is hit, not the amount of margin used. Costs and slippage can still affect the actual loss.

Even with a 5% daily loss limit, the entire US$5,000 is not automatically available to risk on this trade.

The daily loss limit is the account’s risk boundary. Each trade should still have its own risk budget.

Prohibited trading and risk rules may also restrict excessive risk concentration, unusually large positions or gambling-style trading. Staying above the drawdown floor still leaves other rules to meet.

The 1% here is a hypothetical risk budget; it must still fit the account’s limits and remaining loss allowance.

Daily Loss: Floating Losses Count Too

First, distinguish between two figures:

• Balance: The settled amount in the account.
• Equity: The account value including floating profits and losses on open positions.

Suppose today starts with a US$100,000 balance. One trade has US$1,000 of planned stop-loss risk and currently shows a US$400 floating loss, before costs:

The trade is still open, but equity has fallen. The planned US$1,000 stop-loss risk already includes the US$400 floating loss.

Now suppose the daily allowance is fixed at 5% of initial capital, using the balance at the daily reset as the reference. Today’s equity floor is:

US$100,000 − US$5,000＝US$95,000

The floor monitors daily account risk; it does not replace the individual trade’s stop-loss.

Daily loss calculations differ. Confirm:

• Is the reference based on balance, equity, or the higher of the two?
• When does it reset, and in which time zone?
• How are floating profits and losses, commissions, and overnight fees included?

For overnight positions, remember: The daily reference may change, but floating losses do not disappear at the reset.

Static and Trailing Drawdown: What Happens to the Floor as Profits Grow?

A static drawdown floor is usually calculated from initial capital and does not rise with profits.

With US$100,000 of initial capital and a fixed US$10,000 loss allowance, the floor is US$90,000. It stays there even if the account grows to US$102,000.

Trailing drawdown rises with a specified high-water mark. The floor usually does not fall when profits are given back.

Suppose that after a period of trading:

• Highest-ever intraday equity: US$102,500
• Highest-ever end-of-day balance: US$102,000
• Fixed trailing distance: US$10,000

The three hypothetical models would produce these results:

This assumes no condition has stopped the floor from trailing, and that the end-of-day floor has already been updated.

Intraday trailing may count unrealized profits toward a new high. By the time price pulls back, the loss floor may already have risen.

End-of-day trailing does not mean breaches are checked only at the close. Some models update the floor at day-end but can still trigger a breach when intraday equity reaches the active floor.

Beyond the percentage, check what the floor tracks, when it updates and how a payout changes it.

Consistency Rules: Profits Cannot Be Too Concentrated in One Day

Consistency rules usually measure whether profits are overly concentrated.

Suppose a program requires:

The highest single-day realized net profit ÷ cumulative realized net profit must not exceed 50%.

You have made US$1,800 in total, with US$1,000 earned on your best day:

US$1,000 ÷ US$1,800＝55.6%

Looking at this rule alone, you have not yet met the requirement.

Suppose another trading day adds US$200, with the best-day figure unchanged:

US$1,000 ÷ US$2,000＝50%

You now meet the consistency requirement in this example.

This does not mean “I am US$200 short, so I must trade now.” Forcing a trade without a suitable opportunity can disrupt your plan.

Calculations and consequences differ. Missing the requirement may delay passing or payout eligibility, rather than immediately invalidate the account.

Check the percentage, denominator and applicable stage. Cumulative net profit differs from the sum of profits on winning days; “50%” alone does not describe the rule.

Minimum Trading Days and Minimum Profitable Days Are Different

Even after reaching the profit target, you may still need to meet a day-count requirement.

• Minimum trading days: You need qualifying trading activity on a specified number of days.
• Minimum profitable days: A day may count only if its profit reaches a specified amount or percentage.

A small trade does not necessarily count as a profitable day. Holding one position for several days does not automatically complete several trading days.

Day requirements may vary by evaluation stage, funded account or payout route.

When comparing programs, review the conditions separately for each stage:

Apply your records to this table: do you hold overnight, when are profits concentrated, and how much normal drawdown does your method need?

An account is worth comparing further when its rules fit your day-to-day trading.
