Independent intelligence for active traders

Realise your true edge.

Trading costs can quietly turn a winning strategy into a losing one.

Spreads, commissions, overnight financing, FX conversion and slippage are constantly shifting. Blotr tracks them in real time and provides the tools to cut your exposure to the broker, without changing your exposure to the market.

50% of what you make goes to the broker on spread cost.

Have you considered the FX conversion charged on your profit?

Zero-commission just moved the fees elsewhere

Explicit charges became implicit ones. Brokers now have a high incentive to appear inexpensive but a low incentive to be inexpensive.

Frictional drag decides whether you're profitable

Spreads, commissions, overnight financing, FX conversion and slippage compound into the reason active strategies fail.

Comparison sites are paid for by the brokers

Affiliate-driven listings publish static averages and headline spreads, not the full cost structure. This glosses over what is really going to impact your returns.

Costs don't dent returns.
They move the break-even.

A fraction of a pip could be the difference between a winning strategy and a losing one for active traders. Blotr isolates the total transaction cost element and shows its effect on win rate, P&L ratio and return rate.

Identifying the right product can improve your returns without requiring a change to your trading style. Blotr ensures you're not needlessly giving away alpha.
