In cryptocurrency investment, choosing the right trading mode and order strategy is the foundation of profitability. OSL provides two core trading systems tailored to different investor needs: Flash Trade, designed for ultimate efficiency, and Pro Trade, suited for strategic execution.

This article delves into the mechanisms of these two modes and provides a detailed analysis of "Market Orders" and "Limit Orders" within the professional mode.

OSL offers two trading modes, each designed for specific user requirements.

Order Types Explained — Market vs. Limit Orders

In Pro Trade mode, understanding the trigger mechanisms, pros, and cons of different order types is key to avoiding losses and maximizing gains.

1. Market Order: Speed First

• Definition: A Market Order instructs the exchange to buy or sell "immediately at the best available current market price" without setting a specific price.

• Pros: High Certainty of Execution. When speed is more important than price (e.g., entering during high volatility or urgent stop-loss), Market Orders ensure your trade is filled immediately.

• Cons (Slippage Risk): Lack of price control. If market depth is insufficient or volatility is high, the final execution price may deviate from the quote you saw (slippage), increasing transaction costs.

2. Limit Order: Price First

• Definition: A Limit Order instructs the exchange to execute the trade only when the market price "reaches or improves upon" a price you set。

• Pros: Controlled Costs. You can precisely lock in your buy cost or sell profit, avoiding losses caused by slippage.

• Cons (Execution Uncertainty): If the market price never reaches your set value, the order will remain as an "open order" and will not execute, potentially causing you to miss the opportunity.
