Tradewink vs Robinhood: Best AI Trading Platforms 2026

Frequently asked questions

How much should I risk per trade?

A common starting point is 0.5% to 2% of account equity per trade, with the lower end appropriate while you are still validating a strategy. What matters is that the number is fixed in advance and enforced automatically, because the trade you most want to oversize is usually the one you should not. Tradewink computes size from risk-based, ATR-based and half-Kelly methods and takes the most conservative of the three.

Where should I put my stop loss?

At the price that invalidates the reason you entered, not at a round dollar amount that feels tolerable. In practice that usually means beyond a structural level — under the swing low, outside a volatility band, past the opening range. Then size the position so that distance equals your fixed risk amount, rather than picking a size first and squeezing the stop to fit.

What is the pattern day trader (PDT) rule?

A FINRA rule: in a US margin account with under $25,000 in equity, more than three day trades in any rolling five business days flags the account as a pattern day trader and can restrict it. It applies to margin accounts, not cash accounts, and it catches people out constantly. Tradewink counts round trips and blocks the trade that would breach the limit.

Does an AI trading bot manage risk automatically?

It depends entirely on the product — several signal services have no risk layer at all. Tradewink runs risk checks before every order: per-position limits, daily loss limits, sector exclusions, a circuit breaker and PDT enforcement, all evaluated before the order reaches the broker. A rejected trade is a working risk system, not a malfunction.

Is AI trading profitable?

Not inherently. AI improves consistency and coverage; it does not eliminate market risk, spreads, slippage or taxes. A strategy can win 60% of the time and still lose money if the average loss is larger than the average win, which is why expectancy and risk-reward matter more than win rate. Judge any service on resolved outcomes over a full cycle.

What is slippage and how much does it cost?

Slippage is the gap between the price you expected and the price you got, driven by spread, order size relative to available liquidity, and speed of the move. On liquid large caps it is often negligible; on thin names, at the open, or around news it can quietly exceed your entire expected edge. Tradewink models slippage and commission inside position sizing rather than treating fills as free.
