How the ETHUSD lot size is calculated
Position size = risk in dollars ÷ (stop distance × value per unit). On ETHUSD, one point ($1) is worth $1.00 per standard lot, so a $55 stop costs $55.00 per lot. $50 ÷ $55.00 = 0.9 lots (rounded down to the 0.01 step).
Spread add a little to the real cost of each trade, so many traders round down further. Calculated at the current ETHUSD price of 2,365.48.
The $5K rules in ETHUSD price moves
Rules are set in dollars, but you watch the ETHUSD chart. This is how far price can move against a 0.9-lot position before each limit is reached:
- Classic: target $500 ($555.56) + $250 ($277.78), daily loss $200 ($222.22), max loss $400 ($444.44), all with 0.9 lots.
- At 1% risk per trade it takes 4 losing trades in a single day to hit the Classic daily limit.
- 1-Step: target $500 ($555.56), daily loss $150 ($166.67), max loss $300 trailing ($333.33), all with 0.9 lots.
- At 1% risk per trade it takes 3 losing trades in a single day to hit the 1-Step daily limit.
- Ascent: target $250 ($277.78) + $250 ($277.78) + $250 ($277.78), daily loss $150 ($166.67), max loss $300 ($333.33), all with 0.9 lots.
- At 1% risk per trade it takes 3 losing trades in a single day to hit the Ascent daily limit.
- Spark: target $400 ($444.44), daily loss $100 ($111.11), max loss $200 ($222.22), all with 0.9 lots.
- At 1% risk per trade it takes 2 losing trades in a single day to hit the Spark daily limit.
Maximum ETHUSD position size on $5K
With 1:5 leverage one lot needs about $473 of margin, so a $5K account could open about 10.56 lots in total. That is a margin ceiling, not a target: the daily loss limit is the real constraint.
When ETHUSD moves most
Follows Bitcoin’s rhythm, with extra moves around network upgrades and ETF news. Size down around those moments: wider swings mean a wider stop, and a wider stop with the same risk means fewer lots.
