Hi:
The limit on indicator source code is 200...
optInputParameterInfos = new OptInputParameterInfo[] {
new OptInputParameterInfo("ExtDepth", OptInputParameterInfo.Type.OTHER, new IntegerRangeDescription(extDepth, 1, 200, 1)),
new OptInputParameterInfo("ExtDeviation", OptInputParameterInfo.Type.OTHER, new IntegerRangeDescription(extDeviation, 5, 200, 1)),
new OptInputParameterInfo("ExtBackstep", OptInputParameterInfo.Type.OTHER, new IntegerRangeDescription(extBackstep, 3, 200, 1))
};
Not know if it is by performance reasons or not... but you can create a custom indicator with this indicator code changing the limits.
The sorce code is present on JForex API
Trade well
