Sizing for how you trade
Position sizing for scalping
A scalper has the most mental arithmetic to do between trades, and typing it into a calculator is simply not acceptable at that timeframe. ZRisk drastically reduces the numbers you need. Keep more of your edge.
What goes wrong
- A stop two tenths of a percent away, with a round trip costing a tenth, means half your planned risk is commission
- At thirty trades a week the taker rate decides whether a marginal edge is an edge at all
- Typing a size by hand is the slowest step in a process measured in seconds
What ZRisk does about it
Fees inside the risk
Entry and exit commission are part of the number before the size is decided, so a stop-out costs what you planned.
Maker-first entry
The entry is placed post-only and chased at the live price, so it earns the maker rate instead of paying the taker rate. What it saved is recorded per trade.
One press to open
The plan is on screen the whole time. Stop and target go out with the entry.
Scored in R
History adds up in R rather than in dollars, which is the only way to compare a hundred small trades honestly.
In numbers
On $500k of monthly volume, entering as a maker rather than a taker at the standard rates is roughly $75 a month, before anything the sizing itself is worth.
