Add indicators into EA and fix some bugs

I use 2 indicators on the mql5 site as follows

FivePattern - https://www.mql5.com/en/code/7050

CandlePattern - https://www.mql5.com/en/code/19960

and zigzag.

I want to add 3 indicators to my EA

The indicators to add include

1. zigzag add 2 lines

zigzag 1: 12, 5, 3

zigzag 2: 24, 10, 3

2. Five Pattern

param 1: 12, 5, 3

param 2: 24, 10, 3

3. CandlePattern

There are 5 indicators in total

The way to add is as follows

int zigzagHandle_M15 = iCustom(_Symbol, PERIOD_M15, "ZigZag", InpDepth, InpDeviation, InpStep);

int zigzagHandle_H1 = iCustom(_Symbol, PERIOD_M15, "ZigZag", InpDepth2, InpDeviation2, InpStep2);

handle_candle_m15 = iCustom(_Symbol, PERIOD_M15, "FivePattern", ... InpDepth, InpDeviation, InpStep );

handle_candle_h1 = iCustom(_Symbol, PERIOD_M15, "FivePattern", ...InpDepth, InpDeviation, InpStep);

handle_candle_m15 = iCustom(_Symbol, PERIOD_M15, "CandlePattern15");

I want to pass the corresponding parameter

use

ChartIndicatorAdd(ChartID(), 0, zigzagHandle_M15 )

...

to add the indicator to the chart

and use

ChartIndicatorDelete(ChartID(), 0, "FivePatternH1");

...

to delete from chart when switching between timeframes

The error I encountered is that when switching between timeframes, the drawing objects of the old indicator are still there.

I need to fix that error and update me on how to pass parameters + color to the 3 indicator lines above.

A demo is mandatory
