What is the most appropriate way to handle aerial jumps during retesting?

Retest Bitcoin trading strategy, finding the database stored by botvs, occasionally missing data, forming a k-line gap, for example, on March 27 to 28, there was a k-line gap of up to a dozen hours. In retesting, if the jump is open before the air position, and when the k-line is missing, it can not be flattened, affecting the accuracy of the retesting, how to handle this gap better?

var last_ticker_time = new Date (().getTime ((); // records the time the ticker was last accessed function is on Tick ((() { var this_ticker_time = new Date (().getTime ((); if (this_ticker_time - last_ticker_time >= 15 * 60 * 1000) { // two tickers separated by 15 min, that's a jump Log ((exchange.GetTicker)) I'm not sure. last_ticker_time = new Date (); getTime (); and I'm not sure.

function main() { while (true) { onTick() Sleep(60000) } }
