How Number of Decimals Affect the Settings?

From the above example,

1934.352 - 1933.308 = 1.044 about 1000 points.

1933.308 - 1932.308 = 1.000 exactly 1000 points.

Point is the smallest value the EA sees on a chart.

if you have 0.001 on a chart, then 1000 points means 1.000

if you have 0.01 on a chart, then 1000 points means 10.00

Conclusion:

If your broker shows XAUUSD for instance 1780.xxx “Three digits”, Distance, Max Spread and TP values should look as follows:

Distance 1000

Max Spread 5000

TP 1000

Series TP 1000

The above is equivalent to:

If your broker shows XAUUSD for instance 1780.xx “Two digits”, Distance, Max Spread and TP values should look as follows:

Distance 100

Max Spread 500

TP 100

Series TP 100
