Optimize Deriv Dbot for Real-time Trade Execution and Eliminate Tick Delay

A client is experiencing a critical timing issue with their Deriv DBot, specifically the 'Differs Premium' strategy. The bot is designed to track the last two digits of a price feed and trigger a trade when Digit 1 equals Digit 2. While the bot correctly identifies the matching digit condition, trade execution consistently lags by 1 ticks. This delay causes trades to be entered on incorrect digits, missing the intended entry points and impacting strategy performance. The current 'before_purchase' block in the bot's logic does not contain any intentional delay. The project requires a skilled freelancer to diagnose the root cause of this persistent tick delay in trade execution. The primary goal is to implement a solution that ensures trades execute precisely on the same tick the condition is met, thereby eliminating the lag. It is crucial that the existing martingale, stop-loss, and profit-target logic within the bot remain fully functional and are not adversely affected by the proposed timing fix.
