**Cumulative difference**

Cumulative – (lat. Cumulatio increase, accumulation)

**Delta** is the difference between market (non-limit) orders executed at the ASK price and the BID price.

Any transaction on the exchange takes place in the order of turn due to a counter order (limit order).

Counting transactions executed by a market order at the ASK price and at the BID price gives us the formula:

- BID – ASK = Delta

If it grows, then market orders are buying more than selling. Performing someone’s limit sales.

If it falls, it means market sales, perform limit purchases.

Loaded some range. And from the bottom line is immediately built. Each new tick changes the delta value.

At the beginning of the loaded range, the delta value is always small.

On the next candlestick, the delta value will change in a positive or negative direction. Depending on who prevails, market buyers or sellers.

The value of the delta in the current candlestick takes into account the value of the delta in all previous candles.
