//| 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: attach it to any chart to open its window. It never    |
//| trades. The source is open and it uses no DLL. It writes only the |
//| custom symbol (its bars and ticks) - nothing else.                |
