//| Build custom backtesting symbols from your broker's own history:  |
//|   - shift the raw timestamps by hours or days                     |
//|   - rescale / reshape prices with a typed function                |
//|   - write real (transformed) ticks or M1 bars                     |
//| The result is an ordinary custom symbol the Strategy Tester can   |
//| use (Every tick / Every tick based on real ticks / 1 minute OHLC).|
//|                                                                   |
//| A utility indicator: it draws nothing and never trades. The       |
//| source is open and it uses no DLL. It writes only the custom      |
//| symbol (its bars and ticks) - nothing else.                       |
