How to Plot Indicators with Limited Stock Data

Hello,

I am seeking assistance with afl code to correctly plot indicators when there is limited data in the stock array. The weekly trading system uses a new 52 week high and a market regime filter to buy. The market filter is the market index (XAO) above a 30 week SMA (shown as ribbon below). The sell signal is based on a 3xATR(14) Chandelier stop.

In the example below, the stock MP1 commenced trading on 16 December 2015. The market regime ribbon, Chandelier stop line and buy/sell arrows do not display as required for the first 30 bars. A 2 year back-test from 1 Januray 2016 has a buy on 08 January 2016 & sell on 01 April 16 (buy & sell arrows not displaying).

I would welcome advice to correctly code the indicators for the first 30 bars.

Thanks in advance.
