3.16.0
Wick Catcher

The wick catcher allows the user to specify a reference price refresh rate (as a time interval in hrs, mins, secs) and a % distance to track the market.

Wick Catcher Algo

How it Works

If, for example, you place a buy order with a 5-minute price refresh rate and a 3% distance from best bid, the algo places a buy order at 3% below the best bid.

Every 5 minutes, the algo recalculates the order's price based on the best bid and your specified % distance. This works in the opposite direction for sell orders.

This allows you to specify how frequently (time frequency) you want the algorithm to reprice (i.e. track the market) and at what distance (% away), depending on the move you're trying to catch.

Would Fill Price (SmartTwap, AdaptiveChase, TimeSlice, POV)

If enabled, the price at which the remaining quantity can be completed immediately.

When a would fill opportunity occurs, the algo trades aggressively whenever liquidity is available at the would fill price.

Off Book Scale

When enabled, only one limit order will be active on the order book at a time. Subsequent orders will be placed only after the active order is fully executed.

Limit Chase Minimum Chase Size

When enabled, the limit chase algo will only adjust its price if the total quantity at the best bid / offer exceeds the specified min chase size.

This applies to quantity at best bid when buying, and best offer when selling.
