Matsui Securities announced historical simulation for automated FX strategies from 17 October, free for its FX account holders on desktop and mobile. Users can vary the currency pair, period, order range and quantity before comparing profit and required margin.[1]
The operating guide specifies that the margin estimate assumes fixed 25-times leverage. It is a model input, so a trader should not read the displayed requirement as a personalised allowance for losses or a forecast of future funding needs.[3]
Results can be transferred into an order-entry screen with the same settings. That step preserves the distinction between testing a configuration and submitting an order. The guide also allows users to save results as an image, making comparisons between configurations easier.[3]
The accompanying update adds an effective-leverage display to account information. This measures exposure relative to assets in the FX account, giving users a view of their actual position alongside the simulation’s fixed assumption.[2][3]
The useful comparison is therefore between the strategy’s historical behaviour and the capital available to support it. A profitable backtest can still require substantial funding while positions remain open; profit and cash needed to maintain exposure answer different questions.
