Multi-Time Period Chart[1] 3 overlays w/ Halfbacks

These are 3 High-Low ranges that uses the code of TradingView's built-in Multi-Time Period Chart indicator as well as adds on optional midpoint[1] (or "halfback") to the overlays. Finally, there are labels offset on the right margin that indicate the open price for each of those timeframes. One thing I adjusted is that [0] range of each timeframe is omitted. This is because the original TV indicator's boxes have their right edge completely covering the wicks (Thus, the title for this indicator). This script has plenty of utility, but it designed specifically with the STRAT (Rob Smith) methodology in mind.
