CheapTrader 0.2.3

Install

• Installer (CheapTrader-0.2.3-setup.exe) or the portable zip (CheapTrader-0.2.3-win64.zip: unzip anywhere, run CheapTrader.exe).
• You need Windows 10 or 11 (64-bit). For real prices and trading, install MetaTrader 5, log in to a (demo) account and leave it open: the welcome tour finds it by itself.
• Windows may say "Windows protected your PC" because the program is not signed: click More info, then Run anyway. Compare your download with SHA256SUMS.txt (Get-FileHash <file> -Algorithm SHA256).
• Orders from the app are off until you switch them on in the MetaTrader menu. Trading carries a high risk of losing money: try it on a demo account first.

What is in 0.2.3

• An indicator is run over every candle on the chart, not just the newest 500. The page asked for 500 bars
  whatever the chart held, so on a chart of 20,000 candles a line covered the last few percent of it (scroll back
  and it ended), a 200-bar average started late, one over 500 bars or more was empty, and a replay that began more
  than 500 bars back had no indicator line at all. Now the indicator gets as many bars as the chart shows (the bar
  count at the bottom left, 20,000 by default, up to 100,000), and during a replay every bar back to the replay's
  first candle (the lines are still cut at the cursor, so they cannot show the future).
• An indicator that needs more says so. One line at the top level of its code, NEEDS_BARS = 60_000, makes the
  program run it over that many bars (200,000 at most; where the broker has fewer it gets what there is). Only the
  lines over the chart's own bars come back, the older bars warm the indicator up. The screenshot tool (POST /api/snapshot) warms indicators up the same way. The line is read without running the code. See the indicator
  guide, "How many bars df holds".
• The indicators of a chart are run side by side instead of one after the other.
• POST /api/indicators/{id}/run takes a count of up to 100,000 (it was 20,000). An indicator that is too slow
  says over how many bars it timed out; the guide explains what to do about a loop over the bars (it takes seconds
  over 20,000 bars where it took no time over 500).
