To The Moon

The fastest way to blow up a $50,000 trading account is confusing notional position size with actual dollar risk.

Beginners decide how much to buy based on how much money is sitting in their brokerage account. Professional traders decide how much to buy based strictly on the distance to their invalidation level.

If you are buying a fixed dollar amount (or fixed number of shares) on every trade regardless of chart structure, you are trading random variance not a system. $Oracle(ORCL)$

The Paradox: Tight Stops Mean Larger Position Sizes

Here is the counter-intuitive math that trips up almost every new trader.

Assume a $20,000 account with a strict 1% risk cap ($200 max loss per trade):

Scenario A: Tight Scalp Setup $Adobe(ADBE)$

• Entry Price: $100.00

• Technical Stop-Loss: $98.00 (2% stop distance = $2.00/share)

• Position Size: $200 Risk / $2.00 = 100 Shares

• Total Position Value: $10,000 (50% of total account balance deployed)

Scenario B: Wide Swing Setup $Salesforce.com(CRM)$

• Entry Price: $100.00

• Technical Stop-Loss: $80.00 (20% stop distance = $20.00/share)

• Position Size: $200 Risk / $20.00 = 10 Shares

• Total Position Value: $1,000 (5% of total account balance deployed)

Result: In BOTH scenarios, if the trade hits your stop-loss, you lose EXACTLY $200 (1% of your account).

Notice how Scenario A uses 10x more capital than Scenario B, yet carries the exact same risk. This is why sizing based on account percentage allocation without factoring in stop distance leads to wild variance.

The 3 Execution Rules to Fix Your Sizing Today

1. Calculate Risk First, Position Second: Decide your maximum dollar loss (e.g., 1% of account balance) before you even look at entry options.

2. Let the Chart Dictate the Stop: Place your stop-loss where the technical setup is invalid—never move a stop-loss closer or further just to force a desired position size.

3. Use Dynamic Position Sizing: Recalculate your share count or contract size on every single trade using:

Units = (Account Balance * Max Risk %) / |Entry Price - Stop Loss Price|
