Live OP market data, simulated capital, and the fees, spread and price impact a real order would pay — the honest way into Optimism before a wallet is involved.
Optimism is an Ethereum layer-2 rollup and the basis of the OP Stack, a shared framework used by several other networks. OP is its governance token, with a public-goods funding model built into the ecosystem.
OP trades with the layer-2 sector and, like its peers, carries scheduled supply expansion that periodically overwhelms short-term technical structure.
Run a paired simulation of OP and ARB to see how two assets in the same sector diverge on token-specific supply events.
DexLadder does not fill at the mid price. An order is charged the spread, the venue fee and the price impact your own size causes — on pool trades that impact is computed from the constant-product and concentrated-liquidity maths rather than approximated by a flat percentage. That is the difference between a paper result you can trust and one that quietly flatters you. The full model is written up in the methodology.
Work out the position from your stop distance rather than your balance — the position size calculator does it in one step — and if you are using leverage, check the liquidation distance against the ordinary daily range of OP before choosing a multiplier.
Yes. DexLadder needs no signup, no email and no wallet connection — the paper balance and trade history stay in your own browser.
Yes. Prices come from live market feeds; only the money is simulated.
Yes — venue fees, the spread and the price impact your order size causes. An environment that skips those overstates every strategy you test.
