Class ESPTradeTimer

java.lang.Object

com.caplin.motif.fx.ret.fxtrading.submission.esp.ESPTradeTimer

public class ESPTradeTimer
extends java.lang.Object

Contains rules that ensure a trade conforms to gap-time rules.

Use this class to check whether the trade should be rejected because of a gap-time limit.

The gap-time limit is best described as the time a user must wait between one-click trades. If the user tries to submit consecutive trades within the gap-time period, the first trade should pass and the remaining trades should fail. Gap-time is a concept supported in TrAPI, however the native implementation limits trades per proxy-client, which results in unpredictable behaviour when combined with our connection pool model involving shared proxy clients.

There are three settings for gap-time validation

• Same pair -- will limit consecutive trades on the same currency by a user
• All pairs -- will limit consecutive trades globally for a user
• None -- won't limit consecutive trades

There should be one ESPTradeTimer per trade channel.
