How the SOLUSD lot size is calculated
Position size = risk in dollars ÷ (stop distance × value per unit). On SOLUSD, one point ($1) is worth $1.00 per standard lot, so a $3 stop costs $3.00 per lot. $1,000 ÷ $3.00 = 200 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 SOLUSD price of 101.905.
The $100K rules in SOLUSD price moves
Rules are set in dollars, but you watch the SOLUSD chart. This is how far price can move against a 200-lot position before each limit is reached:
- Classic: target $10,000 ($50) + $5,000 ($25), daily loss $4,000 ($20), max loss $8,000 ($40), all with 200 lots.
- At 1% risk per trade it takes 4 losing trades in a single day to hit the Classic daily limit.
- 1-Step: target $10,000 ($50), daily loss $3,000 ($15), max loss $6,000 trailing ($30), all with 200 lots.
- At 1% risk per trade it takes 3 losing trades in a single day to hit the 1-Step daily limit.
- Ascent: target $5,000 ($25) + $5,000 ($25) + $5,000 ($25), daily loss $3,000 ($15), max loss $6,000 ($30), all with 200 lots.
- At 1% risk per trade it takes 3 losing trades in a single day to hit the Ascent daily limit.
- Spark: target $8,000 ($40), daily loss $2,000 ($10), max loss $4,000 ($20), all with 200 lots.
- At 1% risk per trade it takes 2 losing trades in a single day to hit the Spark daily limit.
Maximum SOLUSD position size on $100K
With 1:5 leverage one lot needs about $20 of margin, so a $100K account could open about 200 lots in total. That is a margin ceiling, not a target: the daily loss limit is the real constraint.
When SOLUSD moves most
Most active with the US session and during broad crypto rallies or sell-offs. Size down around those moments: wider swings mean a wider stop, and a wider stop with the same risk means fewer lots.
