Ospe Dual MACD Buy Sell Signal

Two EMA-difference histograms with confirmed crossover labels and historical BUY and SELL boxes.

Ospe Dual MACD plots two MACD-style EMA differences in one separate window: a 12/26 pair and a 5/13 pair by default. It displays colored histograms and matching lines. The color of each histogram changes with its position relative to zero and its movement from the preceding bar.

When the faster difference crosses above the slower difference on a completed candle, the indicator places a green BUY box below that candle. A cross below places a red SELL box above it. Historical boxes are drawn for the selected number of closed candles. The current, incomplete candle does not produce a signal box. Optional pop-up alerts report new confirmed signals after the initial load.

The indicator is visual and does not place, modify, or close trades. The lines are EMA differences; there is no separate smoothed MACD signal line. A crossover is a market observation, not a profit forecast.

Slow pair fast EMA: default 12.
