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. $50 ÷ $3.00 = 16.66 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 101.945.
The $5K 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 16.66-lot position before each limit is reached:
- Classic: target $500 ($30.01) + $250 ($15.01), daily loss $200 ($12), max loss $400 ($24.01), all with 16.66 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 ($30.01), daily loss $150 ($9), max loss $300 trailing ($18.01), all with 16.66 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 ($15.01) + $250 ($15.01) + $250 ($15.01), daily loss $150 ($9), max loss $300 ($18.01), all with 16.66 lots.
- At 1% risk per trade it takes 3 losing trades in a single day to hit the Ascent daily limit.
- Spark: target $400 ($24.01), daily loss $100 ($6), max loss $200 ($12), all with 16.66 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 $5K
With 1:5 leverage one lot needs about $20 of margin, so a $5K 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.
