Bigger funded accounts look better. But the lot size you trade should be based on what you can manage calmly, not on what the account allows.
Questions worth asking:
- What lot size do you trade comfortably with your own money?
- How does the funded account's daily loss limit translate to lots, given your stop size?
- Can you follow your rules at that size, or does it cause hesitation and early exits?
Example: 100k funded account, 5% daily loss limit = $5,000. With 5-pip stops on EURUSD and four losses allowed per day, risk per trade = $1,250, or 2.5 lots. If you're used to trading 0.5 lots, jumping to 2.5 is a big psychological step.
Many traders do better starting at a size closer to their comfort zone, even if the account allows more. Profit grows slower but rules are followed.
A gradual approach: trade 50% of allowed size for the first month. If execution stays clean, move to 75%.
What size did you trade in your first funded month compared with what was allowed?

Re: Funded account size vs a comfortable scalp lot
Before running a strategy at full size, trading it at one tenth of the intended volume for a few weeks costs little and teaches a lot.
What shows up is real execution: slippage, rejected orders, partial fills, widened spreads at odd moments, and the emotional reaction to real money. Each of these changes results.
It also reveals the cost of scale. If a strategy works at 0.1 lot, will it work at 1 lot? Often it does, since retail size is small compared with market depth, but on thinner pairs or around news, the answer can be no.
The test needs a defined plan: number of trades, what's measured, and what result counts as passing. Without that, the trial period turns into drift and nothing is learned.
The results should be compared with the backtest, trade by trade where possible. Where they differ, the reasons often point to flaws in the backtest, such as optimistic fills or bad data.
How long was the trial period before scaling up, and what changed between the test and full size?
