Delta Indicator
Before we dive into the delta indicator for MT4 (MT5), let’s quickly refresh what delta is. Delta is the difference between market buy orders (executed at Ask prices) and market sell orders (executed at Bid prices). The calculation formula is: Delta = Ask - Bid. It’s important to note that only market (and stop) orders are used in the delta calculation.Delta can be positive, negative, or zero. A positive delta on a specific candle indicates that there were more market buy contracts during that period. A negative delta means market sell orders dominated. A zero delta means the number of executed buy and sell contracts was equal.
This raises a natural question — where can you get a delta indicator for the MetaTrader 4(5) Forex terminal?
At the moment, there is only one company — ClusterDelta — that provides delta and cumulative delta indicators for MT4 and MT5. The company delivers real exchange-based data to its indicators in real time.
Delta for MT4/MT5 by ClusterDelta

Cumulative Delta
Cumulative delta is a highly useful exchange-based tool. It calculates the sum of all deltas over a certain period of time and displays it as a rising or falling line that shows whether there are currently more buy or sell orders in the market.The indicator is available in two versions: as a line chart or as OHLC bars. There should be no difficulties installing it in the MT4 or MT5 terminal. In most cases, the indicators work right away after being added to the chart with default settings.

Let’s Summarize
We’ve introduced two valuable exchange-based indicators — delta and cumulative delta. Whether you use them or not is up to you. However, you should understand that trading without real exchange data is like playing the lottery — relying on luck instead of informed decisions.
